allowing undo of column resizes, with .visidatarc addition

[midichef]

After I resize a column, I often want to be able to undo it by hitting U. Here is code to add to your .visidatarc to let that happen.

def mark_cols_width(sheet, cols):
    for col in cols:
        vd.addUndo(setattr, col, '_width', col.width)
Sheet.addCommand('_', 'resize-col-max', 'mark_cols_width(sheet, [cursorCol]); cursorCol.toggleWidth(cursorCol.getMaxWidth(visibleRows)) if cursorCol else None', 'toggle width of current column between full and default width')
Sheet.addCommand('z_', 'resize-col-input', 'mark_cols_width(sheet, [cursorCol]); width = int(input("set width= ", value=cursorCol.width)); cursorCol.setWidth(width)', 'adjust width of current column to N')
Sheet.addCommand('g_', 'resize-cols-max', 'mark_cols_width(sheet, visibleCols); [c.toggleWidth(c.getMaxWidth(visibleRows)) for c in visibleCols]', 'toggle widths of all visible columns between full and default width')
Sheet.addCommand('gz_', 'resize-cols-input', 'mark_cols_width(sheet, visibleCols); width = int(input("set width= ", value=cursorCol.width)); Fanout(visibleCols).setWidth(width)', 'adjust widths of all visible columns to N')
Sheet.addCommand('z-', 'resize-col-half', 'mark_cols_width(sheet, [cursorCol]); cursorCol.setWidth(cursorCol.width//2)', 'reduce width of current column by half')

Thank you for sharing this. I recently resized a column and then wanted to undo it. I will use this.
