[FR] Limit the textbox input when editing a cell to whatever the specified data type is for that column.

When editing a cell, currently I see that it's free text. It would be convenient to limit the user to be able to type in only whatever is the data type for that cell.

So if I'm editing a column that's only numbers, then I should be able to type in only numbers.

Great suggestion! We will add this to our backlog. :)
