For tables with many columns of numbers, the default width of those columns maybe too small, meaning the whole number is not fully visible. The user could resize columns themselves but this is tedious.
As a default, could the column sizes be set to auto-size based on the largest data value? Just like in Excel. For example, a column has the following:
5,000,000
234,000,000
The width of the column would be wider enough to show 234,000,000.
