Change line color of .table-bordered in Twitter Bootstrap

@tableBorder is a variable, not a property.

You can just add this to your CSS:

.differentTable, .differentTable td{
   border-color: black;
}

The best way is

.table {
  border: 0.5px solid #000000;
}
.table-bordered > thead > tr > th,
.table-bordered > tbody > tr > th,
.table-bordered > tfoot > tr > th,
.table-bordered > thead > tr > td,
.table-bordered > tbody > tr > td,
.table-bordered > tfoot > tr > td {
   border: 0.5px solid #000000;
}

.table-bordered td, .table-bordered th{
    border-color: black !important;
}

.table-bordered th : create border for head and foot table.

.table-bordered td : create border for body table

I have to use '!important', because the border wouldn't change without it.
