Word document,When the cursor is on a specific cell in a table, how can we find the previous paragraph object of the table? How can this be implemented using a Python script?

I tried to create a cursor using createTextCursorByRange, but when using this function, either the creation fails or the cursor cannot move out of the table. I’ve tried many methods, but none of them work. This includes using the table cursor of the TextTable object, which also cannot move out of the current table.
