Hi @colin-jpms!
You can try this code
kd-dynamic-table td { border-top: none !important; border-bottom: 1px solid #000000; }
In the CSS code above, we're first removing the top border from the table cells using border-top: none !important;. Then, we're adding a bottom border to the cells with border-bottom: 1px solid #000000;. You can customize the color and thickness of the border to your preference.
Save the custom CSS and preview your Dynamic Table to ensure the bottom border is displaying as expected.
This should add a bottom border to your table cells and remove the top border that's hard-coded by default. If you need to apply a different border style or color to specific cells, you can add additional CSS rules to target those cells by their class or ID.
I hope I was able to help you)
