How do I include a table in another table's cell in Microsoft Report viewer

I am work开发者_JS百科ing on a project which includes creating some reports and I am using Microsoft Report Viewer for this.

Let's say I have Table 1 and I need to put another table let's say Table 2 into a cell of Table 1, when I drag Table 2 into Table 1's referred cell I get the below error

The tablix ‘Tablix1’ has a detail member with inner members. Detail members can only contain static inner members.

How can I achieve this? Is it something about parent groups or child groups?

add a table, add a parent group(rest is another solution) add a child and add a table into the cell
