Word 2002 I have been using a table as a Data Source document for mail merging. Everything was allright until a colleague pasted cells from an Excel document into the table. Now when I try to even sort a column in alphabetic order I get this error: Cannot sort table containing merged cells. I guess the pasting of Excel cells has created merged cells, but I cannot identify which ones they are. Mine is a large Table and to make a new one would take hours of work. I need to fix it urgently. How to indentify the merged cells? Is there a way to DEMERGE cells? Help me please.
