I'm interested in adding a link in a tableselect form row. Utilizing the #options key I can only add columns with strings. I am able to add form elements in the #options array similar to the #rows array.

$rows[$nid] = [
    'edit_link' => [
        'class' => 'edit_link',
        'data' => [
            '#type' => 'link',
            '#url' => Url::fromRoute('group_manager.edit'),
            '#title' => 'test',


$form['table'] = array(
    '#type' => 'tableselect',
    '#header' => $header,
    '#options' => $rows,

Implementing this example as is doesn't render this column in the table, so I assume it has failed somehow.

The 'edit_link' element works if the form is changed to a 'table' instead of 'tableselect'.

    Your code is roughly correct, but there are things you didn't post so I can't say for sure why you're having a problem. Note that classes need to be passed as an array, so that should look like 'class' => ['edit_link']. Also, you only show one column - is that really all your table has? And if the 'group_manager.edit' route needs a parameter (e.g. the group id ?) that needs to be specified in your Url::fromRoute() call ... But as I said, your code is basically correct and should work for a tableselect - I use working code that's very similar to the above. Check your log for errors ...

I solved my issue.

The links column was not rendered for the tableselect form because I didn't update my $header array with the new element name edit_link.

It appears a table form does not map the element names to the header names, meaning I did not have to update the header array for my link columns to appear. As long as the element name was in the header array Tableselect would render the column. I believe this to be the basis of my issue.
