A question about creating custom tables on Dashboard

Hello all,

I am working on creating a Custom table to show a listing of various Database status. But I notice that after I have built the table,

I keep getting a message on the bottom of my table that states:

The resource doesn't show all data.

Is there a way to get the table to show all the data, or is there a limit of how many items it can show?

I'm stumped at the moment. I do have the 'show all records' clicked.

Im kinda new at this.

Im creating a Custom table, which I have been showing up on a dashboard, like so:

It shows a list, and then at the end of it it states:

The resource doesn't show all data.

Any ideas what that means?

Thanks,
