TheFormTool protects the Q&A Table as though it is critical to functioning.
Still, there are times when it's necessary. While not recommended, you can bypass the built-in protections for the Q&A Table by selecting Word>Developer>Design Mode, then selecting and deleting the Table. Some users may need to "customize" their Word ribbon to enable the Developer Tab to show. You can do that by clicking Word>File>Options>Customize Ribbon, then clicking on Developer in the right side window.
