Not sure but try thjs 

=Aggr( Only({<Name = {"=IsNull(Match(Name, 'david', 'Paul', 'Pierre'))"}>} Name),    Name)

I hope in data model both these tables are linked on Field names:-
If there is another Field in table 2 with density 100  percent or a combination of fields with density 100 percent other than field names. Lets name that field FieldA.
try this:-

Aggr(Only({<Names=e({<FieldA={"=(Isnull(FieldA)=0)"}>})>}Names),Names)
or if Field Has Numeric Values then
Aggr(Only({<Names=e({<FieldA={">=0,<=0"}>})>}Names),Names)
