Selection feature breaking first column width

[wattsbn]

If you look at the selection feature in the docs, you can see the id column is about the size of the selection column. Even if you explicitly set its width, it will not be reflected in the grid. This is a recent issue. I have only noticed this within the last day or two.

I saw this one earlier, and thought it had been resolved. I suspect it came about from this commit: #1609, fixing #1608. But I see in #1662 that Julie is having the same issue, so perhaps it didn't even fix that (although it no longer happens for me).

I wonder if the colDef is getting out of synch with the rowHeader, I unshifted the rowHeader to the front of the columns array, and perhaps somehow the size isn't getting applied to the right column. Is maybe the index off by one - I seem to recall at one point it was choosing to start the index at 1 instead of zero?

Yes, I upgraded to latest and it's back in my application too. Looking at the grid, I can see that I have two columns with an index of 0. I thought I'd written code to renumber them all so that wouldn't happen. There is still some divergence in which order columns are created, depending on exactly when your data and columnDefs get set (I think). So sometimes the rowHeader is the first column created, and sometimes it's inserted when columns are already there. I think that's why the difference in behaviour in different scenarios.

Tentative fix, but still has a problem with headers on tutorial 113, so cannot yet be merged.
