How to get css background color on tag to span entire row

Question

I have tried everything I can think of in css in order to get a background color to span an entire table row ( tag) But I keep getting a white border around each

Answer 1

I prefer to use border-spacing as it allows more flexibility. For instance, you could do

table {
  border-spacing: 0 2px;
}

Which would only collapse the vertical borders and leave the horizontal ones in tact, which is what it sounds like the OP was actually looking for.

Note that border-spacing: 0 is not the same as border-collapse: collapse. You will need to use the latter if you want to add your own border to a tr as seen here.
