I would like to have the background color of the column header transparent (instead of the light blue in the screenshot below). Is this possible?
You all have to override or change ng-table.css
.ng-table th.sortable.sort-desc,
.ng-table th.sortable.sort-asc {
background-color: rgba(141, 192, 219, 0.25); <-- remove this or change as per your need
text-shadow: 0 1px 1px rgba(255, 255, 255, 0.75);
}
