Another add-on to tableFilter makes it possible to show/hide columns, I have played some with it and increased the number of columns. This means that a screen need to be 5000 to 6000 pixel wide to see all about 70 columns.

To avoid that I have made it easy to show/hide columns. It was a bit of work because I had to get rid of the plug-ins user interface and supply my own.

Only disadvantage with this is speed, initializing is a bit slow, but I tried it on a smaller computer and a tablet, on both it worked fast enough after loading/initializing.

And with this setup there is no problem including both length and x-length.
