If you downloaded the WooCommerce Product Table plugin from CodeCanyon or similar, unzip the download package first, then upload the real plugin zip. Often there are licensing and documentation and source files included that are not part of the installable.
Thus the final zip should include a single folder as a plugin folder.
If you upload the final zip and have another issue, that is because of:
1- Is there sufficient space on your server or hosting account?
2- If you’re getting a permissions error, you need to contact your web host or server administrator to make sure you have permission to upload plugins.
If you are unable to upload the plugin via the WordPress admin then please follow the instructions in the WordPress Codex to install the plugin manually via FTP
If you have any issues, you can contact us via Support Center.
