Parameters

$header: An array containing the table headers. Each element of the array can be either a localized string or an associative array with the following keys:

"data": The localized title of the table column.
"field": The database field represented in the table column (required if user is to be able to sort on this column).
"sort": A default sort order for this column ("asc" or "desc").
Any HTML attributes, such as "colspan", to apply to the column header cell.

$rows: An array of table rows. Every row is an array of cells, or an associative array with the following keys:

"data": an array of cells
Any HTML attributes, such as "class", to apply to the table row.

Each cell can be either a string or an associative array with the following keys:

"data": The string to display in the table cell.
"header": Indicates this cell is a header.
Any HTML attributes, such as "colspan", to apply to the table cell.

Here's an example for $rows: @verbatim $rows = array( // Simple row array( 'Cell 1', 'Cell 2', 'Cell 3' ), // Row with attributes on the row and some of its cells. array( 'data' => array('Cell 1', array('data' => 'Cell 2', 'colspan' => 2)), 'class' => 'funky' ) ); @endverbatim

$attributes: An array of HTML attributes to apply to the table tag.

$caption: A localized string to use for the <caption> tag.

$cols: An array of table colum groups. Every column group is an array of columns, or an associative array with the following keys:

"data": an array of cells
Any HTML attributes, such as "class", to apply to the table column group.

Each column can be either an empty array or associative array with the following keys:

Any HTML attributes, such as "class", to apply to the table column group.

Here's an example for $cols: @verbatim $cols = array( // Simple colgroup. array(), // Simple colgroup with attributes. array( 'data' => array(), 'colspan' => 2, 'style' => 'color: green;', ), // Simple colgroup with one col. array( array(), ), // Colgroup with attributes on the colgroup and some of its cols. array( 'data' => array(array('class' => 'diff-marker'), array('colspan' => 2)), 'class' => 'funky', ), ); @endverbatim

The HTML will look as follows: @verbatim <table>  <colgroup />

<colgroup colspan="2" style="color: green;" />

<colgroup> <col /> </colgroup>

<colgroup class="funky"> <col class="diff-marker" /> <col colspan="2" /> </colgroup> ... </table> @endverbatim

Return value

An HTML string representing the table.
