straddle_me not only confusing but a lot of time some functionality is not working due to slow updates to table tamer.
since nobody from support have answered anything for 10 days here and I have some free time.
go to settings -> HUD.
1) Add panel
2) Then choose Panel Type -> Table.
3) Then Table Panel Items -> press Add,
4) then from item type choose -> Text.
5) Then in text write for example 33%. - what you write here will be displayed on table.
6) Then On click -> Choose BetPerecent
7) Then Amount -> Write 33
8) Then in appearance you can choose fonts etc.
9) You can also click to display it only Postflop.
10) You can rename this panel so later you now which panel is which
For preflop at step 6 just choose BetXBB instead of BetPercent.
Hope this helps you.
I myself am not using Table Tamers layouts because I use it only for Bodog/Chico/ACR and don't want TT to mess with Stars/888 and Winamax and use StarsCaption instead for resizing.
So I imagine you should be fine not using layout and resizing tables how you want.
