How to set input mask for a cell in a dhtmlx grid?

So I have a dhtmlx grid and one of the columns contains data of type Time. The format is HH:MM. I want to apply an input mask in that cell so the user can only enter two digits, semi-colon (:), and another two digits. I also want the HH:MM to be sort of visible in the cell to give the user a visual cue of what they need to type in it. How do I do that?

Thanks.

dhtmlxGrid doesn’t support input masks
You can use onEditCell event to parse and reformat entered text after user finish the edit operation.
