According to your description, it seems that tables doesn't expand with data entry by using data validation drop-down lists in Microsoft Teams, however, it works fine in Excel client. And you can also typed date manually, it works fine.
If so, we have tested it on our side, we went to Excel client and created a table with data validation drop-down list, then we uploaded this file to Microsoft Teams, then we opened it and selected value from data validation drop-down
list, and we found it works fine, as shown below:
We cannot reproduce the same situation as yours. Given this situation, if you are using Microsoft Teams client, we’d suggest you go to Teams Online to check if the same problem will occur.
If the same problem still persists after trying the suggestions above, to narrow down this issue, could you provide the information below?
- May I know if only this file has this problem? You can create a new file to check if the same problem will occur.
- May I know if this problem also occurs on Teams Online? Could you also provide the version of Microsoft Teams? You can click your avatar in your Teams > About > Version and provide the screenshot of your Teams.
- You can also upload this file to OneDrive for business directly and open it in Excel Online to check if the same problem will occur.
Best Regards,
