FixedHeaders calculate header width incorrectly after inline edit

FixedHeaders calculate header width incorrectly after inline edit

This is similar to https://datatables.net/forums/discussion/comment/116225

I dont have a small test case to replicate this.
I have inline editing enabled for the first column which doesn't have an explicit width as I want it to take up whatever space is left.

On page load, and after the first inline edit, all header widths are correct. You'll notice that the style attribute gets wiped on the second and subsequent inline edits.

Thereafter, the header widths get recalculated wrong each time, and you can see from the debug comment I've included that they change each time.

My work around was to disable fixedHeaders :)

I tried using $(this).width(toWidths[i]); as per the link above but that didn't make any difference either.

Hopefully this is useful to someone on the internet.
