New bug in Origin 2020b.

E.g. big number, e.g. 83859232 which fits in the cell tightly was rounded e.g. to 83959200 by mistake. It should show with scientific notation e.g. 8.38592E7 since in Preferences: Options, Numeric Format tab, we set the upper threshold as 6. Resize column width will fix the issue.

Also there are display issues with German numeric separator. E.g. 898,10906 when resized the column wider, it shows 89810904.

Fixed in Origin 2021.
