Inserted table won't allow changes

WD2003. Two docs: A is a long formatted thing with paragraph numbering, B is
a six-page table.
- Added a section break at the end of A to change page orientation to
landscape
- copied and pasted B's table (or ...)
- Insert File the table file as various formats
The result is a table that is stapled onto a single page in Print Layout
view, the top lined up with the top of the correct page of the receiving
file, but not lined up below the header, and it extends far off the bottom of
that page instead of breaking for page breaks. I can see it all in Normal
view.

That's the problem when I put them together by inserting the table file B
into A, but I have succeeded in doing it the other way around, but then I
lose all the paragraph numbering from A although it kept the headers and
footers.

Please would someone tell me what I'm doing wrong so that I may start
feeling competent again?
