I looked at sorting again (I had tried before) and found out what my problem was.

It looks slightly different now, but sorting works and I discovered that “!important” can be very useful in CSS.
I am still not sure about the length, with the raw length it is basically impossible to make good filters, except if people has to write mathematical expressions. The style I use where it is possible to select one or more predefined values would not work.
If you selection is down to a few batteries it is very fast to check the length, just move the mouse marker over the battery names. I use the same style of popup as on my other tables, this time with the info box.
