Can anyone please help me to render theme_table data in vertical format instead of horizontal format ? Currently horizontal table is overflowing the page and breaking breaking points.

My current code :

    $build['table'] = [
      '#type' => 'table',
      '#header' => $header,
      '#rows' => $rows,
      '#empty' => $this->t('No content has been found.'),

    return $build;

It generates following table but I wanted it in vertical table format.Where header is in left and row is in right instead of header in top and rows at bottom.

I am using Drupal 9.3.9 with Bartik theme.

I can think of a way where I can process array of header and rows and format it to render in vertical format. Before proceeding to that I am searching if we have any core functions which can provide the same functionality. As It would not be efficient to completely rewrite array data.

Horizontal table Overflow

  • Drupal does not really care what data and how many cells you put into rows.... if you want multiple rows instead of cells, provide the corresponing data structure with multiple $rows instead of just one.

Sadly Drupal core does not provide responsive tables.

You'll need to use contrib or custom library solution to solve this issue.

Have a look at these contribs:

  • thanks for the answer but unfortunately it is not what i am looking for. I am mainly looking for a way Where header is in left and row is in right instead of header in top and rows at bottom using core functions if any exists. Mar 29, 2022 at 7:09

    @miststudent2011 To my knowledge, there is no such core function. Another possibility could be to copy core's table.html.twig into your theme and adjust as you like. You could make them <divs> instead of <table>, and theme it with CSS to look like a table.

  • @miststudent2011 Since you control the code, I guess if you go the <div>s route, you might as well create your own custom template rather than using '#type' => 'table',.

  • @miststudent2011 this is all just CSS - Drupal’s included themes don’t have any styles for alternative table layouts so you’ll have to find/provide your own if you still want to use tables. Or create your own markup/styles to fit exactly what you need as suggested. Or take a step back and see if word-wrap: ellipsis doesn’t cover your needs. Drupal won’t help you here as this is fundamentally a styling issue
