Resizable table headers

[camskene]

Inside the developer tools it's possible to resize the table headers in the network tab. The same functionality would be nice to have inside the ember inspector.

I will work on this if there's enough interest. A few people I asked agreed this would be useful to them.

This would be very useful. Right now the only way to read long paths / filenames is to stretch the browser window open across multiple monitors.

It would also be useful if I could choose which columns are visible.

I was looking into the css changes that would need to happen to do some of this and I believe that it would take a lot of work that may conflict with or could be incorporated into the work that @teddyzeenny is doing on the tables right now. he is removing list-view and adding smoke and mirrors (the table addons.).

It would be good to get some input on how do implement this. It might be a good add-on that utilizes mixins, that way it could be plugged into existing tables and add-ons.
