 * Sortable table which can be used for data available in an array.

 * Is a variation of SortableTableFromArray because we add 2 new arrays  $column_show and $column_order
 * $column_show is an array that lets us decide which are going to be the columns to show
 * $column_order is an array that lets us decide the ordering of the columns
 * i.e: $column_header=array('a','b','c','d','e'); $column_order=array(1,2,5,4,5);
 * These means that the 3th column (letter "c") will be sort like the order we use in the 5th column
