how to design the modual?help me

I want to design a moudual which like the Excel of OFFICE of Microsoft,each content in a single grid can be modified ,you also can put some character strings into a single grid,how can I do ?

There isn’t a stock PtTable widget. So you would have to write your own. If you have a small number of grid entries (less then 10x10) then you could probably just use a PtGroup with a bunch of PtText widgets in an NxN layout. Not resizable but it would allow editing.

You don’t say what language you are writing in. If you are willing to use Java, there is indeed a “off-the-shelf” table widget, which allows any type of object in a cell.

I use C,is there exist any widget I can use in PHAB programing?thanke you for your help!
