I have 2 data tables.
for one of them , i would like to insert the whole table to the other data table in one of the columns as you see in the picture.
what is the syntax that i should use in this case, that finally i will get table inside table.
it needs to be done by add datarow activity, api statement used within assign, invoke method or invoke code. The Build datatable wizard is not offering this for us
Not knowing all your requirments, nesting the datatable is not properly reflecting related relations. Having 2 datatables in place and using e.g. a datajoin would be a more clean approach.
What is the purpose, what you want to achive in your datatable related entity model design?
