is it possible?

I found an HTML code online, but it didn't work when I tried to create a table.

Anyone know how?

Thanks

I don't believe that is supported (as HTML). But, you could make a table elsewhere (html, Excel, Word, etc), take a screencapture and upload the image.

You may be able to get something reasonably "okay" using characters such as hyphens ("-") and pipes ("|") but that would be a pretty big pain.
