Deleting columns may cause out-of-memory errors with large datasets

[tanapok]

Description:
Deleting a column can lead to out-of-memory errors when working with large datasets, which ultimately causes Teable to crash. In my case, the table contains about 2 million rows, with only some text columns and no formulas or links.

To Reproduce:
Steps to reproduce the behavior:

1. Set up a Teable instance with some RAM limit (4GB RAM, for instance).
2. Create a table and add 20 text columns.
3. Add over 1 million rows and fill them with data.
4. Delete a column.
5. The application crashes and auto reboot (if set to unless-stopped or always).

Expected behavior:
The column should be deleted successfully.
