It would also be good if the search filter was at the top, and not at the bottom as it is now.

问题 Whats the best way to style the row selection of the primeng datatable grid? I have a checkbox and when selected the row changes to a bootstrap blue. I want to lighten the color for the row selection. How do I do this? 回答1: I'm not sure if you found your answer anywhere, but the CSS you're looking for is this: body .ui-datatable .ui-datatable-data tr.ui-datatable-even.ui-state-highlight { /*background-color handles the color of the highlighted row*/ /*color sets the color of the text*/
