I want toolbars to be created against a flexible grid with the following requirements:
- the total width is variable and should always match the screen even when resizing.
- cells can be combined
- all columns must be the same size (e.g. with three columns)
- same with strings
- total height should optionally match screen height
- these meshes are user generated, so they cannot be hardcoded CSS like online generators do.
Here are some photos that I took:
user-defined grid example 
same merged cell example 
the same example scales 
I am looking for a plugin / code for this, since I am pretty sure that this cannot be done in CSS (the grid layout is not implemented in most browsers as far as I know). The closest I got is to create a table, but the cell size has become complete chaos ( why doesn't this table look neat? ).
