grid.cell, ColumnId parameter / bug or design?

[Jens-dojo]

Hi,

the docs say:
"When columns is an array, the numeric (!!) indices become the column IDs; "

So I thought I could us a NUMBER as ColumnId, for example

var mycell = grid.cell(target,2)

That does not work

var mycell = grid.cell(target,"2")
does work.

If that is not a bug, I propose to make it clear in the APIs that ColumnId must be a string.

It took my quite a while to figure that out ......

Let me know if you want me to change that and make a pull request.

Thank you
Jens
