Lock certain cells in w2ui grid & lock icon in the cell

Question

I have a couple of questions regarding locking (as in not allowing user to modify) entries in w2ui grid:

1. Is there a way to lock a certain cell of an editable column?

   • I know from the documentation that I can lock the whole grid with w2grid.lock method.
   • I should be able to lock one whole row by changing editable: true to false in the record properties.
   • I can also lock a whole editable column by changing editable: true to false.
   • But I can't think of any way to lock one particular cell.

2. How to have the yellow lock icon just like in the picture at the bottom of this page?

Thanks in advance for all the help
