You can insert a Next Page section break (under the Layout tab) before and after your table. Click in the section that contains your table and you can change the orientation for that section alone. If you are using headers/footers throughout the document and with automatic numbering, you will need to adjust the page number to Continue page numbering from the previous section (Insert tab, Page Number in the Header & Footer ribbon). This also applies to your header if you have different headers for different sections. Click on Same as Previous in header and footer, go to the Navigation ribbon (this is under the Design tab), and deselect Link to Previous.
