You can paste text that includes photos, video, and shapes into table cells. The object must be set to “Move with Text,” and the text wrap set to “Inline with Text.”
Select the object or the text that contains the inline object, then choose Edit > Cut or Edit > Copy (from the Edit menu at the top of your screen).
In cells, movies show only the poster image you set—they don’t play. Their properties are retained so that if you copy and paste them from the cell, they play as usual.
Click the cell, then choose Edit > Paste.
Do one of the following:
For an inline object with text: Place the insertion point at the end of the text, then press Delete.
For an inline object with no text: Select the cell, click the Cell tab at the top of the sidebar on the right, side of the Pages window, click the pop-up menu next to Fill, then choose No Fill.
If you don’t see a sidebar, or it doesn’t have a Cell tab, click 
in the toolbar.
You can also fill the background of a cell with an image, so text flows over it.
