This can be a yes and no answer.If you want an include page as the header for a page (much as a shared border might be) you probably will want to put the information into a table, but on the page where it is 'included', it mostly likely will not be placed into a table. The main page can have 'stacked' tables - one below the include page header to have all your content.
If you are using the include page to contain a navigation bar, and only want to set it in one place (a cell) you might only want to put that information on the include page, not necessarily in a table.
If you have a table on the include page, yes it will become a table within a table on the page where it is included.
For example, this page here at the forum, has some information at the very top - a blue bar, and logo etc. This information is probably in an include page, and is a table. On your page, at the very top, insert your include page. Then underneath that insert a new table for your content. (stacked tables)
Hope this made sense.
