Bottom line is that you'll have to write a new css rule for that.
Depending on which bundle of Twitter Bootstrap you're using, you should have variables for the various colours.
Try something like:
.table tbody tr > td {
&.success { background-color: $green; }
&.info { background-color: $blue; }
...
}
Surely there's a way to use extend
or the LESS equivalent to avoid repeating the same styling.
