Don't toggle td/th visibility with jquery; it breaks in flexbox designs

[mariusGundersen]

We use the MiniProfiler in a flexbox heavy page, and this confuses jQuery a bit. When toggeling the show more/show less columns, they don't show correctly. When showing the columns they get the style display: block instead of display: table-cell (or just having the style removed).

This might be fixed in a newer version of jQuery, but the best practice about this is to toggle a class name instead of trying to show/hide the cells directly.
