Tables Without Borders

Yesterday I spent several hours searching the web, trying out what I found, and then searching these forums trying to find a way to create a table without borders in WordPress, something that I thought should be simple. The instructions I found on the web all seemed out of date because their examples didn’t match up when I tried to use them.

Then I found some forum messages that seemed to solve the problem, but they only gave incomplete instructions, so I’m still frustrated many hours later. What I found said to use this CSS:

(.no-border table, .no-border th, .no-border td { border: none; })

but it didn’t say how to add it to the post that I’m writing.

So all I want to do is display two different English translations of the same passage side by side, and I think a borderless table is the best way to do that. Can someone please tell me how to do that or suggest an alternate approach?

Thanks.
