// ZEBRA-STRIPING
// --------------

// Default zebra-stripe styles (alternating gray and transparent backgrounds)
.table-striped {
  > tbody {
    > tr:nth-child(odd) {
      > td,
      > th {
        background-color: @table-bg-accent;
      }
    }
  }
}



// HOVER EFFECT
// ------------

// Placed here since it has to come after the potential zebra striping
.table-hover {
  > tbody {
    > tr:hover {
      > td,
      > th {
        background-color: @table-bg-hover;
      }
    }
  }
}



// TABLE CELL SIZING
// -----------------

// Reset default table behavior
table col[class^="col-"] {
  float: none;
  display: table-column;
}
table {
  td,
  th {
    &[class^="col-"] {
      float: none;
      display: table-cell;
    }
  }
}
