Hi @dandandsan ,
Could you tell me:
- What is your connector? (Did you use onedrive connector?)
- Did you delete the record in Excel? Did this record in the gallery just become a blank record ?
If my assumption is correct, there are two important points.
- Firstly, Close your table.
- Secondly, refresh your data source.
I've made a test for your reference:
1\ This is my table “Van” and my gallery control.


2\Add an Icon control and set is onselect property to:
Refresh(Van)
3\ Firstly, I opened the table and deleted the third line (third record). Then closed the table. Finally, I clicked the refresh icon.

4\ The result is as follows:

In addition, sometimes "onedrive" has a delay. Please wait a while and click the refresh icon again.
Hope this helps.
Best Regards,
Wearsky
