Recently i had to build a custom simple table in a drupal 8+ installation that would be used as an api feed bridge between drupal 8+ and a custom api feed service. This is the code i used for the custom table with an extra tip for the date field since there is no date type by default in drupal.

Step 2 – Create a php file named MymoduleForm.php in mymodule/src/Form and place the following code.
Drupal offers a mechanism in the backoffice to control the display of blocks, but it is sometimes necessary to set up a little more complex logic.
Here we are going to hide the "id_block" block from the "header" region when we are on an "article" type node via the HOOK_preprocess_page hook:
Content blocks are blocks that you create in the interface. They are much like nodes configurable data structures, with fields etc. If you want to render one of these, you can do what you would normally do with entities, load them and render them with the view builder:
