Sure, I can help you with that! Here are the steps to make a table collapsible in Microsoft Word:

1. First, select the rows or columns that you want to make collapsible. You can do this by clicking and dragging your mouse over the rows or columns, or by clicking on the row or column headers to select them.
2. Once you have selected the rows or columns, right-click on them and select "Table Properties" from the dropdown menu.
3. In the Table Properties dialog box, click on the "Row" or "Column" tab, depending on which one you selected in step 1.
4. Under the "Options" section, check the box next to "Allow row to break across pages" or "Allow column to break across pages", depending on which one you selected in step 1.
5. Click "OK" to close the Table Properties dialog box.
6. Now, when you view your table in Print Layout view, you should see a small arrow icon next to the row or column headers that you selected in step 1. Clicking on this arrow will collapse or expand the rows or columns that you selected.

That's it! You should now have a collapsible table in Microsoft Word. Let me know if you have any other questions or if there's anything else I can help you with.
