I'm looking for a usabillity feature known from desktop spreadsheet applications:

When double clicking a collumn header it should get as wide as the content (like spreadsheets do and any operating system).

I've read this in the EXT-JS forum: “If the content of the last column is wider than the column-width then I can double-click the column-right-side to auto-set the width of the column to the content of the widest cell in this column.“

… so if I move the mouse to the right of a table header column, the column resizability is recognized and the mouse pointer is changed to a resize pointer.

… so the only thing that is missing is to resize the column on double click to the width of the largest cell content for that column.

Kind regards,

Klaus.
