function theme_table
Returns HTML for a table.
Parameters
array $variables: An associative array containing:
- 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"). Only one column should be given a default sort order because table sorting only applies to one column at a time.
- 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.
- "no_striping": a boolean indicating that the row should receive no 'even / odd' styling. Defaults to FALSE.
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:
$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' => array(
'funky',
),
),
);
- footer: An array of table rows which will be printed within a <tfoot> tag, in the same format as the rows element (see above). The structure is the same the one defined for the "rows" key except that the no_striping boolean has no effect, there is no rows striping for the table footer.
- attributes: An array of HTML attributes to apply to the table tag.
- caption: A localized string to use for the <caption> tag.
- colgroups: An array of column groups. Each element of the array can be
either:
- An array of columns, each of which is an associative array of HTML attributes applied to the COL element.
- An array of attributes applied to the COLGROUP element, which must include a "data" attribute. To add attributes to COL elements, set the "data" attribute with an array of columns, each of which is an associative array of HTML attributes.
Here's an example for $colgroup:
$colgroup = array(
// COLGROUP with one COL element.
array(
array(
'class' => array(
'funky',
),
),
),
// Colgroup with attributes and inner COL elements.
array(
'data' => array(
array(
'class' => array(
'funky',
),
),
),
'class' => array(
'jazzy',
),
),
);
These optional tags are used to group and set properties on columns within a table. For example, one may easily group three columns and apply same background style to all.
- sticky: Use a "sticky" table header.
- empty: The message to display in an extra row if table does not have any rows.
Return value
string The HTML output.
