Posted 8 April 2019, 6:42 am ESTThis is observed for SpreadJS 9 (gcspread.sheets.9.40.20161.5.js). In a sheet, when I group certain columns, using showRowRangeGroup and showColumnRangeGroup methods, save the sheet, reopen the sheet and then when I hit the '+' sign sometimes the column widths are lost. Please see one example in the attached snapshot.
Is there a way to retain column widths during grouping? I am trying to look into your documentation but unable to get any hints so far. Please advise.
