How to change the content of the table in the Text box of docX file

Question

How to change the content of the table in the Text box of docX file?When xmlcursor.getobject () instanceof XmlAnyTypeImpl is instanceof XmlAnyTypeImpl, I cannot change the contents of the table in the text box. How can I change the contents of the table in the text box?Here's my code, but he can't change it properly。
