how to control each cell

hello.

i want to control not column but each cell

for example, like under the image.

if check box is checked, then i can input COMMENT like the CONFIRM Sales Team 1, 2.

however, if check box is not checked, then cannot input COMMENT like Sales Team 3.

i use many event method but it control data per column.

To sum up, i want to edit cell about able, disable, type and so on.

Please give me solution.

You may control the checkbox (un)checking with the onCheck event:

Also you may control all the edit operations with any cell using the onEditCell event:
