Describe the bug

When customizing the USWDS theming through the provided Sass variables, the $theme-table-border-color variable is not applied in the node_modules/uswds/src/stylesheets/core/placeholders/_table.scss file. This means the variable can't be used to customize the table border color.

Steps to reproduce the bug

1. Setup USWDS to compile CSS from Sass files/variables.
2. Add a table component to a page.
3. Customize the $theme-table-border-color Sass variable.
4. Compile the Sass into CSS.
5. See that the table color did not change to the customized color.

Expected behavior

The $theme-table-border-color changes the border color of table elements.

System setup

• 2.12.2
• Mac
• 11.6
• Chrome 95

Additional context

The line where the table border color is being applied appears to be line 89 of the node_modules/uswds/src/stylesheets/core/placeholders/_table.scss file:

  th,
  td {
    background-color: color($theme-body-background-color);
    border: 1px solid $table-text-color;
    font-weight: fw("normal");
    padding: units(1) units(2);
  }

where it seems to always be applying the table text color as the border color.
