Finally we have the ability to merge the cells of a table in Google Docs. A table with merged cells has cells that can span multiple rows and/or columns.
To merge table cells, highlight the cells to be merged in your table:
Then right click and select Merge Cells from the menu. The cells will be merged and their contents concatenated:

Again the content is concatenated in the merged cell:
Usefully, merged table cells can now be imported from Word documents too.
