I'm not well experienced in CSS, could somebody tell me how could I override styling so that a cell called "Existing Price Breaks" retains it's left border? Similarly the one below would do the same, splitting the content. But the rest of the header should stay without them as it is now.
Here's the fiddle: http://jsfiddle.net/kacpr/YkL5j/2/
That's the part I would like to override on the 'cell' level:
.table > thead > tr > th, .table > thead > tr > td {
border: 0;
}
