How to create a gridview ? about nuklear

Unfortunately there is no such widget in place (there were some disagreements what should be the feature set of a minimal grid widget, but because Nuklear matured, I think we could afford also such complex widgets - feel free to make a PR 😉).

How to do such widget? Well, I think your approach is not bad. The only thing many people struggle with is the changes (the x- and/or y- overall size of the grid, the column and/or row order, the cell merges & splits, etc.). But this has actually a simple solution - just make indexing indirect by one more "higher level" dereference. Imagine you could access your data only by using the A1 (CD153, etc.) notation. In that case you'd have a function taking such string as an argument (together with a pointer to the "object" holding all the actual data) and returning a currently valid pointer to the underlying plain array of cells (or any convenient data structure). This function resembles a hash map of pointers to the actual data. Such addressing scheme handles changes, merges/joins, splits etc. quite well, is more or less efficient and not so difficult to implement.

Actually I just need to display my data in grid format, not really make an excel like app. If I can have a label with borders and background color I'll be satisfied. Is there a widget like that ? I don't mind using low level stuff.

Is there a widget like that ?

There are several types of buttons (changing theme before and after button calls could imitate no reaction to mouse hover etc.) and other rectangular widgets. You can always ignore/clear mouse input when using them, so to make them "static" (non-changing). There is of course also low level stuff, but I think it's not needed. Just look at Nuklear examples, demos, backends and of course the source code of nuklear.h itself and you'll find your way pretty quickly 😉.
