For the actual results tables I use the coding included in the advanced reply - if you reply to this with a quote you should get the coding for the tables. I copy and paste it into a word document for the betting league, and it's pretty self-explanatory how to add an extra row (copy and paste a previous one and replace it with the new data you want, in case it's not!).
