  // Account for multiple tbody instances
  tbody + tbody {
    border-top: 2px solid @table-border-color;
  }

  // Nesting
  .table {
    background-color: @body-bg;
  }
}



// Condensed table w/ half padding
// -------------------------------

.table-condensed {
  thead,
  tbody,

// Bordered version
// ----------------

      > th,
      > td {
        border: 1px solid @table-border-color;
      }

// Zebra-striping
// --------------

// Default zebra-stripe styles (alternating gray and transparent backgrounds)

      > 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;
