On most well-coded themes, all you have to do is paste this code: <!––nextpage––> wherever you want the next page to start. The pagination will automatically show up. Note: make sure that you are using the Text view rather than Visual view in your post editor.
If for some reason, pagination is not showing up after you have pasted the next page tags, then you would need to add the following code in your single.php loop.
Tables can't be imported directly. Please insert an image of your table which can be found here.
Once you add that, then the pagination will start to show. There are several parameters for this function that you can use. The codex page for Styling Page-Links does a good job explaining that.
