java - Using Data in a Tree in an addRow() function

Question

So I have a flextable and I am trying to add a row. The data I want to input into the cells is located within a tree. I can't seem to find a way to bring the data over into my equation. Any help?

Here is the tree holding some sample info.

private Node root = buildTree();

private Node buildTree()
{
    Node root = new Node();
    root.id = "Main Component";
    root.data = new String[]{ "example", "example", "example", "example", "example", "example", "example"};

    Node child1 = new Node();
    child1.id = "Part 1";
    child1.data = new String[]{ "example", "example", "example", "example", "example", "example", "example"};
    root.children.add(child1);

    Node child11 = new Node();
    child11.id = "Part 1-1";
    child11.data = new String[]{ "example", "example", "example", "example", "example", "example", "example"};
    child1.children.add(child11);

I want to be able to call addRow() to add a row to my table, I'm just stuck as to how to get the information within the arrays in the nodes.

private void addRow(Node nde)
{
    //add first row of data, pull information from the tree
}

Any help is greatly appreciated
