# Reactable
[](https://travis-ci.org/glittershark/reactable)
[](https://codeclimate.com/github/glittershark/reactable)
Fast, flexible, and simple data tables in React.
Reactable allows you to display tabular data client-side, and provides sorting,
filtering, and pagination over that data. It uses the power of [React.js][react]
to do all this very, very quickly, and provides an API that makes simple things
easy, while trying to get out of your way as much as possible if you want to do
something complicated or unconventional.
[react]: http://facebook.github.io/react/
This project is currently alpha-stage, which means the API may or may not be
unstable and there might be hidden bugs lurking around any corner. I'll try to
tag any releases with breaking changes, however, and the more people who use
this the faster we can get to 1.0!
**Note:** As of version 0.12.0 Reactable will only continue to support React
0.14 and higher.

## Installation
### Using Bower
```sh
bower install [--save] reactable
```
### Using NPM
```sh
npm install [--save] reactable
```
Or, you can just download the raw file
[here][build-file].
That file can be used either as an AMD module, as a CommonJS module in Node, or,
if neither are supported, will register the Reactable object as a property of
the `window` object.
Reactable also exposes a set of CommonJS modules for piece-by-piece use with
Node, Webpack, Browserify, etc. These modules are located in the [`lib` folder
at the root of this repositiory][lib-folder].
Keep in mind that Reactable depends on the latest version of React (0.14), which
can be downloaded [here][download]

## Usage
The simplest example:
```jsx
var Table = Reactable.Table;
ReactDOM.render(
<Table className="table" data={[
{ Name: 'Griffin Smith', Age: 18 },
{ Age: 23, Name: 'Lee Salminen' },
{ Age: 28, Position: 'Developer' },
]} />,
document.getElementById('table')
);
```
While pretty basic, this example demonstrates a couple things:
- Columns in the data array can be in any order, and you can omit any you like
- Regular React DOM attributes such as className will pass-through to the
rendered `<table>`
- Data values can be any type with a `toString()` method
### Further Customization
You can also manually build up your rows using `Reactable.Tr` nested in a table,
also using the `data` prop, but this time containing only one javascript object.
This approach can be freely combined with the `data` property on the `<Table>`,
and is useful if you want to specify per-row attributes such as classes, like so:
```jsx
var Table = Reactable.Table,
Tr = Reactable.Tr;
ReactDOM.render(
<Table className="table" data={[
{ name: 'Row one', content: 'These are regular data rows' },
{ name: 'Row two', content: 'They work like above' },
]} >
<Tr className="special-row"
data={{ name: 'Other Row' , content: 'This is a different row' }} />
</Table>,
document.getElementById('table')
);
```
### Even More Customization
If you want to customize the rendering of individual columns, you can go a level
deeper by embedding a `Reactable.Td` inside your `Reactable.Tr`. These have the
required `column` property, and an optional `value` property if you want to
customize the data that's used for sorting and filtering - if the latter isn't
specified, the data used will default to the `Td`'s children.
Example:
```jsx
var Table = Reactable.Table,
Tr = Reactable.Tr,
Td = Reactable.Td;
ReactDOM.render(
<Table className="table" id="table">
<Tr>
<Td column="Name" data="Griffin Smith">
<b>Griffin Smith</b>
</Td>
<Td column="Age">18</Td>
</Tr>
<Tr>
<Td column="Name">Lee Salminen</Td>
<Td column="Age">23</Td>
</Tr>
<Tr>
<Td column="Position">Developer</Td>
<Td column="Age">28</Td>
</Tr>
</Table>,
document.getElementById('table')
);
```
### Customizing Columns
To override inferring the column list from the attributes of the passed `data`
objects, you can either:
- Pass a `columns` array property to the `<Table>` component, which can be
either:
- An array of strings, in which case only the given properties will be included
as columns in the rendered table.
- An array of objects, each of which must have a `key` and `label` property.
The `key` property is the attribute of the row object from which to retrieve
value, and the `label` is the text to render in the column header row.
- Define a `<Thead>` component as the **first child** of the `<Table>`, with
`<Th>` components as children (note the exclusion of a `<Tr>` here),
each of which should have a "column" property. The children of these `<Th>`
components (either strings or React components themselves) will be used to
render the table headers. For example:
```jsx
var Table = Reactable.Table,
Thead = Reactable.Thead,
Th = Reactable.Th,
Tr = Reactable.Tr,
Td = Reactable.Td;
ReactDOM.render(
<Table className="table" id="table">
<Thead>
<Th column="name">
<strong className="name-header">First Name, Last Name</strong>
</Th>
<Th column="age">
<em className="age-header">Age, years</em>
</Th>
</Thead>
<Tr>
<Td column="name" data="Griffin Smith">
<b>Griffin Smith</b>
</Td>
<Td column="age">18</Td>
</Tr>
<Tr>
<Td column="name">Lee Salminen</Td>
<Td column="age">23</Td>
</Tr>
<Tr>
<Td column="position">Developer</Td>
<Td column="age">28</Td>
</Tr>
</Table>,
document.getElementById('table')
);
```
In this example, the `position` column will **not** be rendered.
### Additional node types
Reactable also supports specifying a `<tfoot>` for your table, via the
`Reactable.Tfoot` class. Per the HTML spec, there can only be one `<Tfoot>` per
table and its only children should be React.DOM `<tr>` elements (**not**
`<Reactable.Tr>` elements).
### Preventing escaping of HTML
If you don't want to go all the way down the JSX rabbit hole to render
individual cells as HTML, and you know your source data is safe, you can wrap
strings in `Reactable.unsafe` to prevent their content from being escaped, like
so:
```jsx
var Table = Reactable.Table,
unsafe = Reactable.unsafe;
ReactDOM.render(
<Table className="table" id="table" data={[
{
'Name': unsafe('<b>Griffin Smith</b>'),
'Github': unsafe('<a href="https://github.com/glittershark"><img src="https://d2k1ftgv7pobq7.cloudfront.net/images/services/8cab38550d1f23032facde191031d024/github.png"></a>')
},
{
'Name': unsafe('<b>Ian Zhang</b>'),
'Github': unsafe('<a href="https://github.com/lofiinterstate"><img src="https://d2k1ftgv7pobq7.cloudfront.net/images/services/8cab38550d1f23032facde191031d024/github.png"></a>')
},
]}/>,
document.getElementById('table')
);
```
You can also pass in `unsafe` strings as column labels or in a `<Reactable.Th>`
### Pagination
You can also use pagination, by just specifying an `itemsPerPage` argument to
the `<Table>` component. Include an optional `pageButtonLimit` argument to
customize the number of page buttons in the pagination, which defaults to 10.
For example:
```jsx
<Table className="table" data={[
{ Name: 'Griffin Smith', Age: '18' },
{ Age: '23', Name: 'Lee Salminen' },
{ Age: '28', Position: 'Developer' },
{ Name: 'Griffin Smith', Age: '18' },
{ Age: '30', Name: 'Test Person' },
{ Name: 'Another Test', Age: '26', Position: 'Developer' },
{ Name: 'Third Test', Age: '19', Position: 'Salesperson' },
{ Age: '23', Name: 'End of this Page', Position: 'CEO' },
]} itemsPerPage={4} pageButtonLimit={5} />
```
You can also change the default text on the buttons by including the
`previousPageLabel` and `nextPageLabel` props.
### Sorting
To enable sorting on all columns, just specify `sortable={true}` on the
`<Table>` component. For further customization, ie disabling sort or using a
custom sort function on a per-column basis, you can pass an array to `sortable`,
which contains either string column names or column objects.
We've pre-built some sort functions for you.
- `CaseInsensitive` will sort strings alphabetically regardless of
capitalization (e.g. Joe Smith === joe smith)
- `Date` will sort dates using JavaScript's native Date parser (e.g. 4/20/2014
12:05 PM)
- `Currency` will sort USD format (e.g. $1,000.00)
- `Numeric` will parse integer-like strings as integers (e.g. "1")
- `NumericInteger` will parse integer strings (use `Numeric` if you might have floats)
To specify a custom sort function, use the following structure for the column
object:
```jsx
{column: 'Column Name', sortFunction: function(a, b){
return a > b ? 1 : -1;
}}
```
You can also specify a default sort by passing in either a column name by
itself, or an object with a column and a `direction` paramenter of either `asc`
or `desc`. If no direction is specified, the default sort will be ascending.
Example:
```jsx
{column: 'Column Name', direction: 'asc' }
```
Combined example:
```jsx
<Table className="table" id="table" data={[
{ Name: 'Lee Salminen', Age: '23', Position: 'Programmer'},
{ Name: 'Griffin Smith', Age: '18', Position: 'Engineer'},
{ Name: 'Ian Zhang', Age: '28', Position: 'Developer'}
]}
sortable={[
{
column: 'Name',
sortFunction: function(a, b){
// Sort by last name
var nameA = a.split(' ');
var nameB = b.split(' ');
return nameA[1].localeCompare(nameB[1]);
}
},
'Age',
'Position'
]}
defaultSort={{column: 'Age', direction: 'desc'}}/>
```
In case you are constructing your table without the data attribute, and the
cells contain some additional HTML elements, you can use the value property
on the Td element to define the value to sort for.
In the following example we define two TDs, where the first contains some
additional markup. We tell the Td to take "Griffin Smith" as value for data
handling (filter or sort).
```jsx
var Table = Reactable.Table,
Tr = Reactable.Tr,
Td = Reactable.Td;
ReactDOM.render(
<Table className="table" id="table" sortable={true}>
<Tr>
<Td column="Name" value="Griffin Smith">
<div>
<span>Some Text or Icon</span>
<b>Griffin Smith</b>
</div>
</Td>
<Td column="Age">18</Td>
</Tr>
</Table>,
document.getElementById('table')
);
```
There is also an boolean `defaultSortDescending` option to default the sorting
of a column to descending when clicked:
```jsx
<Table className="table" id="table" data={[
{ Name: 'Lee Salminen', Age: '23', Position: 'Programmer'},
{ Name: 'Griffin Smith', Age: '18', Position: 'Engineer'},
{ Name: 'Ian Zhang', Age: '28', Position: 'Developer'}
]}
sortable={[
'Age',
'Position'
]}
defaultSort={{column: 'Age', direction: 'desc'}}
defaultSortDescending
```
### Filtering
You can do simple case-insensitive filtering by specifying a filterable property
on the table. This property should contain a list of columns which the filter
is performed on. If the filterable property is provided, then an input box with
class reactable-filter-input will be prepended to the thead of the table.
Example:
```jsx
<Table className="table" id="table" data={[
{'State': 'New York', 'Description': 'this is some text', 'Tag': 'new'},
{'State': 'New Mexico', 'Description': 'lorem ipsum', 'Tag': 'old'},
{'State': 'Colorado',
'Description': 'new description that shouldn\'t match filter',
'Tag': 'old'},
{'State': 'Alaska', 'Description': 'bacon', 'Tag': 'renewed'},
]} filterable={['State', 'Tag']} />
```
There is also a `filterBy()` function on the component itself which takes a
single string and applies that as the filtered value. It can be used like so:
```jsx
var table = ReactDOM.render(
<Table className="table" id="table" data={[
{'State': 'New York', 'Description': 'this is some text', 'Tag': 'new'},
{'State': 'New Mexico', 'Description': 'lorem ipsum', 'Tag': 'old'},
{'State': 'Colorado',
'Description': 'new description that shouldn\'t match filter',
'Tag': 'old'},
{'State': 'Alaska', 'Description': 'bacon', 'Tag': 'renewed'},
]} filterable={['State', 'Tag']} />,
document.getElementById('table')
);
table.filterBy('new');
```
You can also pass in a `filterBy` prop to control the filtering outside of the
`Table` component:
```jsx
var table = ReactDOM.render(
<Table className="table" id="table" data={[
{'State': 'New York', 'Description': 'this is some text', 'Tag': 'new'},
{'State': 'New Mexico', 'Description': 'lorem ipsum', 'Tag': 'old'},
{'State': 'Colorado',
'Description': 'new description that shouldn\'t match filter',
'Tag': 'old'},
{'State': 'Alaska', 'Description': 'bacon', 'Tag': 'renewed'},
]} filterable={['State', 'Tag']}
filterBy="new" />,
document.getElementById('table')
);
```
If you are using your own input field to control the `filterBy` prop, you can
hide the build-in filter input field with the `hideFilterInput` prop:
```jsx
var table = ReactDOM.render(
<Table className="table" id="table" data={[
{'State': 'New York', 'Description': 'this is some text', 'Tag': 'new'},
{'State': 'New Mexico', 'Description': 'lorem ipsum', 'Tag': 'old'},
{'State': 'Colorado',
'Description': 'new description that shouldn\'t match filter',
'Tag': 'old'},
{'State': 'Alaska', 'Description': 'bacon', 'Tag': 'renewed'},
]} filterable={['State', 'Tag']}
filterBy="new"
hideFilterInput />,
document.getElementById('table')
);
```
These can be useful if you want to roll your own filtering input field
outside of Reactable.
You can also provide your own custom filtering functions:
```jsx
<Table className="table" id="table" data={[
{'State': 'New York', 'Description': 'this is some text', 'Tag': 'new'},
{'State': 'New Mexico', 'Description': 'lorem ipsum', 'Tag': 'old'},
{'State': 'Colorado',
'Description': 'new description that shouldn\'t match filter',
'Tag': 'old'},
{'State': 'Alaska', 'Description': 'bacon', 'Tag': 'renewed'},
]}
filterable={[
{
column: 'State',
filterFunction: function(contents, filter) {
// case-sensitive filtering
return (contents.indexOf(filter) > -1);
}
},
'Tag'
]} />
```
Your filter function must return a boolean. Refraining from specifying a custom
filter function will default to case-insensitive filtering.
### Empty Data Sets
If the table is initialized without any `<Tr>`s or with an empty array for
`data`, you can display text in the body of the table by passing a string
for the optional `noDataText` prop:
```jsx
var table = ReactDOM.render(
<Table
className="table"
id="table" data={[]}
noDataText="No matching records found." />,
document.getElementById('table')
);
```
### Events
You can pass functions to the following props of `<Reactable.Table>` to provide
event handlers.
#### onSort
Called when the sorting in the table changes.
This handler will be passed an object that contains the column name that is
being sorted by, and the direction it is being sorted:
```js
{
column: 'Name',
direction: -1
}
```
#### onFilter
Called every time the filtering changes.
This handler will be passed a string containing the text that's being used for
filtering.
#### onPageChange
Called every time the page changes.
This handler will be passed a number representing the current page, zero based.
