/**

 * Returns HTML for a table.

 *

 * @param 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.

 *     See theme_table() for a $rows example.

 *   - footer: An array containing the table footer. 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 footer

 *       cell.

 *   - 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.

 *     See theme_table() for a $colgroup example.

 *     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 string

 *   The constructed HTML.

 *

 * @see theme_table()

 * @ingroup theme_functions
