@hucq_landray_com_cn,
Thanks for the template file and screenshots.
Please try our latest version/fix Aspose.Cells for Java v22.8 (Download | Maven). I have tested your scenario/case a bit and could not find the issue (as per your screenshots).
Let us know if you still find any issue with latest version/fix.
