Nesting table headers

Does anyone know how to nest table headers?
I am trying to move my personal finance tracking over from Excel to Coda and have not figured this out yet. See attached picture for details of my request.

Hello @Dillon_Solliday,

Here is one potential way you could structure it using Top and Left Groupings. In the example below “Balances” is your real table, and “Dashboard” structures it in the style you desire, thanks!
