I have a table that acts like it's two separate tables, i.e., when I insert a
new row, the last three columns don't have the inserted row. When I look at
the table in Table Design, the first few columns are called Table1, but the
last three columns are called Table 39. Also, there is a little blue symbol
in the lower right corner of what would be the last cell of Table1 and Table
39.

How can I get this to act as if it is one table?
