      If you only want to show the children of a particular node of the tree then setting the tree model on the QTableView and setting QTableView::setRootIndex() to the index of the parent node should do it.

        it works partially, I want to show all the child of the node in column but is showing all the child as Row
        like i RootNode A having 4 child my table after setting rootIndex as rootNode is showing all four child as 4 rows of one column, how can I show that as one row of 4 column?

          You will need a proxy model to transpose rows for columns. Here's an example for a strictly tabular model that you may be able to use as a starting point:

              Note that it won't work out of the box, as the model you're trying to transpose is (part of a) tree, not a table. So, you'll need to adapt the proxy to basically also get a setRootIndex, and only transpose anything under that index.
