This appiies too Calc Version: 6.4.2.2
The attached spreadsheet has one column, taken from another, larger and more complex spreadsheet. The problem is this: When I clicked on Format/Columns/Optimal Width, I erased the default added value and inserted 0.0". The column actually widened! I tried various variations and never could get the column to adjust to a tolerable minimum width.
This sort of thing has happened with other columns, especially when I tried it with more than one column. Is this a bug, or am I doing something odd with the entries in the cells?
