How do I paginate through multiple pages and collect information from tables?

I am trying to scrap a data set from Family search. however it stops after 2 pagination clicks and it also only shows a portion of the data. I need to go through all pages of this particular collection and make a full data set.

{"_id":"family_search_tables","startUrl":["FamilySearch: Sign In table","tableDataRowSelector":"tr.ng-scope","tableHeaderRowSelector":"tr","columns":[{"extract":true,"header":"Name","name":"Name"},{"extract":true,"header":"Sex","name":"Sex"},{"extract":true,"header":"Age","name":"Age"},{"extract":true,"header":"Death Date","name":"Death Date"},{"extract":true,"header":"Death Place","name":"Death Place"},{"extract":true,"header":"Birth Year (Estimated)","name":"Birth Year (Estimated)"},{"extract":true,"header":"Certificate Number","name":"Certificate Number"}]}]}
