This demo shows how you can theme AdapTable using the shipped 'Dark Theme'. You can select this as your theme in the Theme State.
When you use this theme (or the Light Theme) AdapTable will automatically update the theme of the vendor grid to match your choice.
AdapTable manages theming through CSS variables; we created the Dark Theme just by setting a few properties (mainly colours).
You can create your own themes based on this or others (see the other demos in this section).
