Creating Custom Forms with Tables in Drupal 8, 9, and 10
Wembassy shared a comprehensive blog post authored by Chris McIntosh on creating a custom form in Drupal 8, 9, or 10, focusing on incorporating form elements within a table. The post details setting up a custom module named custom_table_form, including its file structure and necessary configurations in custom_table_form.info.yml.
The guide walks through implementing the form with a class ExampleForm.php, which builds a form featuring a table with items and select dropdowns for updating item statuses. Each step is elaborated, from defining the form and adding table rows to handling form submissions and displaying messages. Additionally, it covers defining a route in custom_table_form.routing.yml to access the form and instructions for enabling the module and accessing the form via the specified path. This detailed tutorial aids developers in enhancing their Drupal projects with organized and interactive forms.
