Migrate Your Tables
In some cases you will need to export your tables from your old site and import them into your new site. If you’re not seeing your tables in the TablePress menu in the left sidebar, return to your old site and use TablePress > Export a Table to download copies of your tables. Then on your new site, use TablePress > Import a Table to upload your tables.
Note: If you upload tables, you may have to edit the table ID number to correctly match how it is referenced on pages.
