I have a simple grid with forceFit config set to true. I experiencing cells layout issue if flex setting is not defined on one of the grid's columns. The following example shows that cell headers are correctly stretched to fit the grid width but it's not the case for grid cells.

Setting flex on a column fix the bug.


As a side note, if you double click on the resize area of one of the cell to auto size it the column header disappear!
