I'm trying something very simple to understand what's going on:

1. I create a new Angular project with ng new
2. After setting the configuration of the project, I install the dependencies with npm i bootstrap
3. I know there are many ways of adding bootstrap to the project. I'm using the method of adding the following code to the styles.scss file: @import '~bootstrap/scss/bootstrap'; (I've also tried to add the dependencies to the angular.json file)

I'm trying to create a table with a dark header (thead-dark) and the table is being created, but the theme not applied.

Expected result

Actual result

CodePudding user response：

npm i bootstrap will install you the latest version of Bootstrap which is 5. Bootstrap 5 does not include thead-dark class and that is why your header isn't rendering dark.

Since you are using Bootstrap 5 you should be using table-dark class instead of thead-dark.

See documentation at: Bootstrap 5 Tables (thead)

<table >
  <thead > <!-- change this -->
    <!-- -->
  </thead>
  <tbody>
    <!-- -->
  </tbody>
</table>
