By far we prefer you put it in code block text. (Use something like "Note" from MS, etc).
Once you type in the format, it will stay formatted when inserted (use the "#" to induce the correct code you're using)
It's great once you set it up, because as you add columns to your UOA files, it will auto align everything as you add stuff.
You can also cut/paste into a jpeg using snipit or such tool; then post as an image. This is quicker, but not able to be edited once posted, so you cannot "add" info as the UOAs progress or if you want to modify stuff.
