How to set the css for tablesorter and bootstrap?

Question

Tablesorter could make the sorting correctly in bootstrap 2, but I couldn't find out how to set the color and caret of table header.

The most likely css I found here is:

table .header {
    cursor: pointer;
}

table .header:after {
  content: "";
  float: right;
  margin-top: 7px;
  border-width: 0 4px 4px;
  border-style: solid;
  border-color: #000000 transparent;
  visibility: hidden;
}

table .headerSortUp, table .headerSortDown {
  background-color: #f7f7f9;
  text-shadow: 0 1px 1px rgba(255, 255, 255, 0.75);
}

table .header:hover:after {
  visibility: visible;
}

table .headerSortDown:after, table .headerSortDown:hover:after {
  visibility: visible;
  filter: alpha(opacity=60);
  -moz-opacity: 0.6;
  opacity: 0.6;
}

table .headerSortUp:after {
  border-bottom: none;
  border-left: 4px solid transparent;
  border-right: 4px solid transparent;
  border-top: 4px solid #000000;
  visibility: visible;
  -webkit-box-shadow: none;
  -moz-box-shadow: none;
  box-shadow: none;
  filter: alpha(opacity=60);
  -moz-opacity: 0.6;
  opacity: 0.6;
}

but with no luck.

Could anyone share the success story?

Answer 1

Maybe it's supposed to be added on the the original style.css file (demo):

/* tables */
table.tablesorter {
    font-family:arial;
    background-color: #CDCDCD;
    margin:10px 0pt 15px;
    font-size: 8pt;
    width: 100%;
    text-align: left;
}
table.tablesorter thead tr th, table.tablesorter tfoot tr th {
    background-color: #e6EEEE;
    border: 1px solid #FFF;
    font-size: 8pt;
    padding: 4px;
}
table.tablesorter thead tr .header {
    background-image: url(bg.gif);
    background-repeat: no-repeat;
    background-position: center right;
    cursor: pointer;
}
table.tablesorter tbody td {
    color: #3D3D3D;
    padding: 4px;
    background-color: #FFF;
    vertical-align: top;
}
table.tablesorter tbody tr.odd td {
    background-color:#F0F0F6;
}
table.tablesorter thead tr .headerSortUp {
    background-image: url(asc.gif);
}
table.tablesorter thead tr .headerSortDown {
    background-image: url(desc.gif);
}
table.tablesorter thead tr .headerSortDown, table.tablesorter thead tr .headerSortUp {
    background-color: #8dbdd8;
}
table .header {
    cursor: pointer;
}

/* bootstrap */
table.tablesorter .header:after {
    content: "";
    float: right;
    margin-top: 7px;
    border-width: 0 4px 4px;
    border-style: solid;
    border-color: #000000 transparent;
    visibility: hidden;
}
table.tablesorter .headerSortUp, table .headerSortDown {
    background-color: #f7f7f9;
    text-shadow: 0 1px 1px rgba(255, 255, 255, 0.75);
}
table.tablesorter .header:hover:after {
    visibility: visible;
}
table.tablesorter .headerSortDown:after, table .headerSortDown:hover:after {
    visibility: visible;
    filter: alpha(opacity=60);
    -moz-opacity: 0.6;
    opacity: 0.6;
}
table.tablesorter .headerSortUp:after {
    border-bottom: none;
    border-left: 4px solid transparent;
    border-right: 4px solid transparent;
    border-top: 4px solid #000000;
    visibility: visible;
    -webkit-box-shadow: none;
    -moz-box-shadow: none;
    box-shadow: none;
    filter: alpha(opacity=60);
    -moz-opacity: 0.6;
    opacity: 0.6;
}

Also, if you want to add any additional HTML inside the header, there is an undocumented onRenderHeader option that you can use to add, for instance, a span inside each header (ref):

$(function(){
  $("table").tablesorter({
    onRenderHeader: function(){
      this.prepend('<span class="icon"></span>');
    }
  });
});

Answer 2

I faced the same Problem and found a very simple solution:

table.tablesorter thead tr .header {
    background-image: url(../img/tablesorter-bg-grey.gif);
    background-repeat: no-repeat;
    background-position: center right;
    cursor: pointer;
    min-width: 30px;
}
table.tablesorter thead tr .headerSortUp {
    background-image: url(../img/tablesorter-asc-grey.gif);
}
table.tablesorter thead tr .headerSortDown {
    background-image: url(../img/tablesorter-desc-grey.gif);
}

You have to add to your sortable Tables the class "tablesorter" of course. I've altered the images, you should adjust the imagefilenames to the standard images included.
