If you want to have multiple 'table' formats that are independent of each other, you basically have two options - use a:
1. separate worksheet for each table; or
2. single worksheet, with each table diagonally offset from the others.
Of course, if your data are suitably arranged for output to Word and you're amenable to that, a Word document can have tables with multiple-width columns and multiple-height rows, including support for merged & split cells. And, of course, Word tables simply appear sequentially in a document and you can use Tables of Contents, etc, for navigation between them.
