Styling
The bundle supports 7 DataTables CSS frameworks out of the box. The Stimulus controller automatically detects which stylesheet you have loaded and picks the matching JavaScript integration — no PHP configuration required.
How It Works
On page load, the controller scans the loaded stylesheets and matches the CSS file’s URL against known patterns. The first match wins, so more specific patterns (e.g. bootstrap5) are checked before less specific ones (e.g. bootstrap). If nothing matches, the bundle falls back to the DataTables default theme.
Switching Frameworks
With AssetMapper
Edit assets/controllers.json to enable the CSS file for your target framework and disable the others:
With Webpack Encore
Import the CSS directly in your entry file:
// assets/app.js — enable exactly one:
import 'datatables.net-dt/css/dataTables.dataTables.min.css'
// import 'datatables.net-bs5/css/dataTables.bootstrap5.min.css'
// import 'datatables.net-bm/css/dataTables.bulma.min.css'
Supported Frameworks
| Framework | Key | CSS file | NPM package |
|---|---|---|---|
| DataTables (default) | `dt` | `dataTables.dataTables` | `datatables.net-dt` |
| Bootstrap 5 | `bs5` | `dataTables.bootstrap5` | `datatables.net-bs5` |
| Bootstrap 4 | `bs4` | `dataTables.bootstrap4` | `datatables.net-bs4` |
| Bootstrap 3 | `bs` | `dataTables.bootstrap` | `datatables.net-bs` |
| Bulma | `bm` | `dataTables.bulma` | `datatables.net-bm` |
| Zurb Foundation | `zf` | `dataTables.foundation` | `datatables.net-zf` |
| jQuery UI | `jqui` | `dataTables.jqueryui` | `datatables.net-jqui` |
| Semantic UI | `se` | `dataTables.semanticui` | `datatables.net-se` |
Framework Setup
The bundle ships with the dt and bs5 packages pre-registered in the importmap. For any other framework, you need to install the required packages first.
DataTables Default
No extra setup. Works out of the box.
Bootstrap 5
Included by default. Make sure Bootstrap 5 CSS is also loaded in your application.
Bootstrap 4
php bin/console importmap:require datatables.net-bs4
Bootstrap 3
php bin/console importmap:require datatables.net-bs
Bulma
php bin/console importmap:require datatables.net-bm
Zurb Foundation
php bin/console importmap:require datatables.net-zf
jQuery UI
php bin/console importmap:require datatables.net-jqui
Semantic UI
php bin/console importmap:require datatables.net-se
Installing Extension Packages
Each extension (Select, Responsive, Buttons, etc.) also has framework-specific packages. If you use extensions, install the matching variants alongside the core package.
For example, with Bulma:
php bin/console importmap:require datatables.net-bm
php bin/console importmap:require datatables.net-select-bm
php bin/console importmap:require datatables.net-responsive-bm
php bin/console importmap:require datatables.net-buttons-bm
# Add other extensions you use…
The naming pattern is always datatables.net-{extension}-{key}.
Customising the Table Element
Override the default CSS classes applied to the <table> element globally in config/packages/data_tables.yaml:
data_tables:
template_parameters:
class: 'table table-striped table-hover'
Or per table in Twig:
{{ render_datatable(table, {'class': 'table table-bordered table-sm'}) }}
Troubleshooting
”No DataTables stylesheet detected”
If you see this warning in the browser console, it means no recognised DataTables CSS file was found in the page’s loaded stylesheets. The bundle falls back to the dt theme.
Common causes:
- The CSS entry in
controllers.jsonis set tofalsefor all entries - The CSS file failed to load (check the Network tab for 404s)
- The stylesheet is loaded after Stimulus initialises (ensure CSS loads in
<head>)
Styles look wrong after switching frameworks
- Make sure only one CSS entry is enabled in
controllers.json - Clear the Symfony cache:
php bin/console cache:clear - For AssetMapper, reimport assets:
php bin/console asset-map:compile
Extension styling doesn’t match the framework
Each extension must use its framework-specific package. If the extension JS and CSS packages don’t match your active framework, you’ll see styling inconsistencies. Re-run importmap:require for the correct -{key} variants.
