Table pasted from EXCEL spreadsheet into Word won't join table created from in Word.

I have a Word document with a table in it that I created from scratch in Word.  Then I pasted a table from an EXCEL spreadsheet into the Word document below the table created in Word, and I can't get the EXCEL table to join the Word table, even with the two tables' "Text wrapping" set to "None".  When I delete the paragraph mark at the end of the Word table, the first character in the top left cell of the table from EXCEL gets deleted, and the two tables won't join.  But if I delete the table pasted from EXCEL, and create a table from scratch in Word, and delete the spaces between the two tables they do join, so I know how to make two tables join, just not if the bottom one is an EXCEL-created table.  Can someone tell me how to let the EXCEL table join the Word table?  Is it maybe because the EXCEL table might have automatic links, or something else attached to it from EXCEL?  It is a simple table with only text and no formulas.  Thank you.
