TablePress ADA accessibility

Hi,

thanks for your post, and sorry for the trouble.

Most of these should be fulfilled already:
– th elements are only used in the table header row, which can be turned off.
– A summary is not automatically added, but can be added e.g. with this piece of PHP code in your theme’s “functions.php” file:

function ada_tablepress_add_summary( $table_attributes, $table, $render_options ) {
	$table_attributes[ summary'] = $table['description'];
	return $table_attributes;
}
add_filter( 'tablepress_table_tag_attributes', 'ada_tablepress_add_summary', 10, 3 );

(The table description will then be used as the summary.)
– A caption is added if you turn on the “Table Description” checkbox.
– colgroup and col elements are not supported at the moment, but often not necessary.
– TablePress uses these elements in the header, footer, and body.

good tip.
Adding to the ADA issue above for TablePress, any good solution for following item?
– Data tables that contain both row and column headers use the scope attribute to identify cells.

Thanks,

Hi,

for the new question: Not directly. You would have to implement this directly using a filter hook, tablepress_cell_tag_attributes defined here.

good pointer, but is it possible if you give me more details on doing so in the code? appreciate your help.

Hi,

no, sorry, I don’t have an example available here. You would need to write a PHP function that hooks into that filter and then makes the necessary code additions.

Hi,
When I am using tablepress_cell_tag_attributes in my functions.php, I am trying to add the scope=”col” to particular rows but I am unable to do so. Below is the code I am using

function ada_tablepress_add_scope( $tag_attributes, $row_idx ) {
    if ($row_idx === 0) {
        $tag_attributes['scope'] = "col";
        return $tag_attributes;
    }
}
add_filter( 'tablepress_cell_tag_attributes', 'ada_tablepress_add_scope' );

I am getting the below error

Warning: Missing argument 2 for ada_tablepress_add_scope(), called in /var/www/public/wp-includes/class-wp-hook.php on line 288 and defined in /var/www/public/wp-content/themes/xxxxxxxxx/functions.php on line 99

Notice: Undefined variable: row_idx in /var/www/public/wp-content/themes/xxxxxxx/functions.php on line 100

Fatal error: Uncaught TypeError: Argument 1 passed to TablePress_Render::_attributes_array_to_string() must be of the type array, null given, called in /var/www/public/wp-content/plugins/tablepress/classes

Please let me know how to get around the above issue.
Thank you.

Hi,

you are very close! As that filter hook uses more parameters, we need to adjust for that:

function ada_tablepress_add_scope(  $tag_attributes, $table_id, $cell_content, $row_number, $col_number, $colspan, $rowspan ) {
    if ( $row_idx === 1 ) {
        $tag_attributes['scope'] = "col";
        return $tag_attributes;
    }
}
add_filter( 'tablepress_cell_tag_attributes', 'ada_tablepress_add_scope', 10, 7 );

Node the longer list of parameters and the 10, 7 parameter in the add_filter call that is necessary to tell WordPress to actually fill all parameters with values.
Then (which actually looks like a mistake by me in the plugin code), the row and column numbers are not the index, i.e. they start with 1 instead of 0.
