Thanks Hound bot!

This doesn't seem like the right solution in the code. I haven't tested this, but it could probably all be reduced to something like maybe?

.table-borderless {
  td, th {
    border: 0;
  }
}

All we need to do is override the default .table styles, so perhaps compare against that opening .table ruleset?

I guess it should work without the explicit tbodys. Thanks for the time @mdo, Updating my PR

Making myself a note that this needs docs for when we're ready for it.

@Varunram: can you add the new class in our docs?

[houndci-bot]

Expected newline after "," selector-list-comma-newline-after
Expected single space after "," in a single-line list selector-list-comma-space-after

[Varunram]

Sure, let me rebase the PR on dev and revert all redundant commits.

@mdo: LGTY?

@mdo @cvrebert Is this to be added in a future release?
