This also isn't for a webpage design. I'm working with a tool that produces an HTML output (for example. that can be used for an email). The fix may not be available, but doesn't hurt to ask.
I've attached a little paint drawing what I want (LookNFeel) and what I currently get (LookNotFeel)
I approached first having 3 columns, but I could not figure out how to line up the data in the second column to the first column. So if we can solve this, then there is not reason for what I am trying currently.
Anyways, so I changed the approach to the sub table in the row, which resolves lining up data from Col1 and Col2.
When placing the column border between those cells, it has the issue of not spanning from row to row, when the data on the right stretches the table out.
Thanks again.
