first, we set up a data area in the table and select it, then click "Insert" to open the "camera" as shown below.
Second, in the table in a blank position to pull out a "camera" diagram, photography is taken by the data area just established.
Changing the data in the data area will reveal that the camera diagram also has the same change in the data area.
Four, when the "camera" diagram dragged to the original data area overlap, there will be a downward layer of overlapping of the contents of the photo.
Five, in the original data area to add graphics, "Camera" also appears the same graphics, when the background is inserted as well.
For this "camera" tool for our work has no real effect, this small part of the book does not think much of the practical value, can not do much to help. If a friend in that area feel that can play a very good help, welcome to exchange.
