How to copy a table row and paste it into another row

1. Verify you have the Document Toolbar open under Window > Toolbar > Document (should be checked) and select Design View from the Document Toolbar.

2. Click and drag from the first cell of your table row through the cells you want to copy. A black border will appear around the selected cells.

3. Hit Ctrl + C or Edit > Copy

4. Click and drag through the rows you want to paste into/over. They will highlight with a black border. 

5. Hit Ctrl + V or Edit > Paste. Keep in mind, the number of cells being pasted over must match the number of cells you copied or you will get an error about the contents of the clipboard not matching.

If you are in Live View, table cells won't highlight when using the above method. The Live View Editor's method is a bit different and, well, clunky...

1. Select the table, so a blue tab and outline appear around it.

2. Click the small 3 bar menu icon in the blue tab to activate table editing. The table cells should all receive a thick black border.

3. From there you can highlight the cells the same way as Design (though the highlight will now be blue), but they will paste in addition to the existing cells, rather than over them.

4. Highlight and delete the ones you wanted to paste over.

To complete what @Nancy OShea said, I don't think there is a direct shortcut for this kind of manipulation, but it's a quick action, for this, two methods :

switch to Code mode

• look for the TR tag corresponding to the row you want to move or clone
• select the whole TR tag
• copy it, or cut it, according to your wishes (Ctrl or Cmd + C or X)
• place the cursor after the closing of the TR tag  (</tr>) corresponding to the row after which you want to place your new row
• paste your clipboard (Ctrl or Cmd + V)

switch to Creation mode

• Hover over the left border of the row you want to clone or move
• the mouse cursor will turn into a black arrow
• click, the row will then be selected
• copy or cut this row (Ctrl or Cmd + C or X)
• place your cursor in the row according to where you want to place your new row
• right click and choose the menu Table > Insert a new row
• a new empty row will appear
• select it
• paste your clipboard (Ctrl or Cmd + V)

Does this help you?

Adobe Support Agents are for account, billing  & activation issues.  They do not teach people to use the software.  In fact most have probably never used the software in production.

If you want to copy content from one location to another, use keyboard shortcut Ctrl + C to copy, Ctrl + V to paste.

Open table in Code View. 

Copy desired <tr> ..... </tr> tag. 

Move to your insertion point and paste.

That said, tables are not for layouts.  They are for tabular data like spreadsheets and charts. Is that what you're building?
