Database can’t be repaired

I hope I have the right version of WP listed. I can’t access wp-admin. This is on a site that was running flawlessly up until I got notice from a monitor on November 16th that it was down.
This is very strange. I have backups going all the way back to April, 2017, but none of them have the tables being requested. I have checked in PHPMyAdmin and run a check in SQL, all reporting the tables are missing. I can’t explain why they aren’t in the backups, either. I have followed the instruction messages from WP and get the following message:
Some database problems could not be repaired. Please copy-and-paste the following list of errors to the WordPress support forums to get additional assistance.
wp_users: Table ‘blackti8_wrd2.wp_users’ doesn’t exist
wp_usermeta: Table ‘blackti8_wrd2.wp_usermeta’ doesn’t exist
wp_posts: Table ‘blackti8_wrd2.wp_posts’ doesn’t exist
wp_links: Table ‘blackti8_wrd2.wp_links’ doesn’t exist
wp_options: Table ‘blackti8_wrd2.wp_options’ doesn’t exist
wp_postmeta: Table ‘blackti8_wrd2.wp_postmeta’ doesn’t exist
wp_terms: Table ‘blackti8_wrd2.wp_terms’ doesn’t exist
wp_term_taxonomy: Table ‘blackti8_wrd2.wp_term_taxonomy’ doesn’t exist
wp_term_relationships: Table ‘blackti8_wrd2.wp_term_relationships’ doesn’t exist
wp_termmeta: Table ‘blackti8_wrd2.wp_termmeta’ doesn’t exist

I hope this is the right place and that someone can help. Otherwise, I am looking at a full reinstall, and there’s a lot going on on this site.

Please note that I run other WP sites on the same servers and have not had any problems with missing tables.

Thanks.

Dave
