Hi,
thanks for your question, and sorry for the trouble.
I assume that something is interfering with the internal save process here.
Can you therefore please try again after temporarily deactivating all other plugins and after switchting to a WordPress default theme like Twenty Sixteen? That way, we can find what’s causing this.

I did find a solution to the problem. After reading through previous posts on this same subject, it said that the problem was solved by making sure there was text in the description area.
I also found that one of my tables had too many columns.
Once I removed the table with the large number of columns and added descriptors to the other tables, I was able to save the tables.
But that leaves the question, if a table is too large, what is too large? And if one table is too large, why does it cause a problem with every other table not being able to be saved?
Are there a specific number of columns and rows that are allowed in a table?
Thank you for your assistance and suggestions. I did not deactivate plugins and change the theme, I deleted the large table and that found the first half of the problem. Reading previous posts gave me the second half to fix this issue.
Hi,
thanks for the update! Those are nice findings!
Yes, this could indeed been caused by the description being empty then. I had ruled that out initially, because you had talked about the description field being used. Sorry for that wrong interpretation.
Basically, this is caused by some server configuration that is not passing the description field as “empty”, but merely as “non-existant”. :-/
So, using an arbitrary description should work around this.
For the table size: There’s no limit for the number of rows or columns in TablePress. However, there are limits on the server, e.g. the PHP Memory or the size of a transfered variable in an HTTP request. Unfortunately, it’s not possible to put that into numbers, as each server is different.
A good starting point is to increase the PHP Memory Limit, by increasing the value of the WP_MEMORY_LIMIT constant in the wp-config.php file, e.g. to 512M, via the instructions from https://codex.ww.wp.xz.cn/Editing_wp-config.php#Increasing_memory_allocated_to_PHP
