How to create a gridview ?

If I want to create a grid interface like excel, how should I do it ?
I can approximate it by using nk_group with NK_WINDOW_BORDER | NK_WINDOW_NO_SCROLLBAR flag but creating unique name for each group is a pain especially if the number of grid can change in runtime.

The issue only identifies nk_group with NK_WINDOW_BORDER | NK_WINDOW_NO_SCROLLBAR as the current approximation; no source file or test is named. Start by reviewing Nuklear's existing grid-related API surface and determine the intended runtime behavior. Done should be a clear approach for creating a variable-size Excel-like grid without unique group names.
