Allow column groups to be collapsed and expanded in the exported table. This would make wide tables easier to navigate and reduce visual clutter when many columns are present.

Add a simple setting to turn word wrap on or off for the whole table. This helps control row height and improves readability when working with long text values.

Column widths in the HTML export are currently fixed. It would be helpful to adjust column widths to improve readability, especially for wider values like dates.
