Excel object has been inserted into word and can be edited; After saving and resizing, you can open it again or double-click to edit it; However, sometimes it is found that the excel object has become a picture and cannot be edited by double clicking (the same is true when inserting visio objects). The above problems were discovered when I was writing my thesis. So far there is no solution! Another method is to save each excel and visio object to be inserted as a file. When you need to edit, please re-edit these saved files and insert them again. I don't know how Microsoft designed it. What a big trouble! !
