Tips for making the first two columns of a datatable stand out with a unique color scheme

I'm attempting to customize the appearance of the datatables' CSS. Specifically, I want the first two columns to stand out by highlighting them in grey, while keeping the rest of the columns in their default color.

Here is the code snippet I tried using:

.grey {
  background-color: rgba(128, 128, 128, .25);
}

<table>
  <colgroup>
    <col class="grey" />
    <col class="grey" />
    <col />
    <col />
    <col />
    <col />

  </colgroup>
  <thead>

However, it seems that the datatables' default CSS is overriding my custom changes.

Answer №1

If you're facing issues with your datatables css being overwritten, one solution is to use chrome devtool to identify which selectors are causing the conflict. To give your selector more weight, try adding additional selectors to your css.

For instance, if the datatables css is

.datatable colgroup col {bg-color:xxxx}

, you can modify your css to

.datatable colgroup col.grey {bg-color:xxx}

to resolve the issue.

Another workaround, although not recommended, is to add !important to your css properties:

.grey {
      background-color: rgba(128,128,128,.25)!important;
    }

Instead of using class names like the one mentioned above, it is recommended to use more descriptive names.

Consider the following alternatives:

table colgroup[semantic class name if necessary] col:nth-child(1),
table colgroup[semantic class name if necessary] col:nth-child(2) {
      background-color: rgba(128,128,128,.25);
}

or

table colgroup[semantic class name if necessary] col:first-child,
table colgroup[semantic class name if necessary] col:first-child+col {
      background-color: rgba(128,128,128,.25);
}

If possible, you can simplify the code by omitting the colgroup and col tags:

table td:first-child,
table td:first-child+col {
      background-color: rgba(128,128,128,.25);
}
