This article
describes how we can show a tablix inside a tablix. Cascade tablix report is
very useful in such cases where we need to show summary and detail data within
the same report. One tablix can be used for summary data and another tablix can
be used for detail data. The advantage of this kind of report is that we don’t
need to create sub report to show detail data.
Let’s
consider the below data for the article. Below table having information about
Country, city and its population with respect to male and female:

summary data and second tablix showing detail data.

created row of first tablix. We can remove country column as it is already
available in first tablix.
