Unfortunately, the only real solution is to change the content so it doesn't spill out over the end of the page. This might be done by making more than one table with a summary table and a breakdown of detail in a following table, or might be handled through endnotes, or if it is about various regions, break it into regions.
If you are trying to do a book that already has tables that are like this, images are probably the only solution, but the type will be small.
Tables are a real sore spot in epubs with problems you have encountered in layout, but also in support by various devices.
