Hi,
When you create a Linked element it creates a Input Control in the report. So here are the steps.
Create a variable saying
[Variable1]=If Pos(ReportFilterSummary();"No Filter")=0 Then 1 Else 0
Then Right click on your 2nd layout table and Select "Format Table" and check the options "Hide When Empty " and also "Hide When following formula is true" under that you need to write formula If =[Variable1]=0 and click ok.
To test the results when you open the report in View mode Clear the filters from Input Control and you will not see the 2nd layout. Once you select the value from table 1 then only second will appear.
Hope this helps.
Regards
