How create a TreeTable in DebugSession

I'm looking for a way to create a TreeTable in intellij Plugin.
The Tab in the DebugSession can I create in *com.intellij.xdebugger.XDebugProcess#createTabLayouter*, but I cant' create a TreeTable inside that JPanel.

My View looks like this:

    <?xml version="1.0" encoding="UTF-8"?>
        <form xmlns="http://www.intellij.com/uidesigner/form/" version="1" bind-to-class="debugger.ui.RegisterViewSessionTab">
          <grid id="27dc6" binding="content" layout-manager="GridLayoutManager" row-count="1" column-count="1" same-size-horizontally="false" same-size-vertically="false" hgap="-1" vgap="-1">
            <margin top="0" left="0" bottom="0" right="0"/>
            <constraints>
              <xy x="20" y="20" width="500" height="400"/>
            </constraints>
            <properties/>
            <border type="none"/>
            <children>
              <scrollpane id="86eac">
                <constraints>
                  <grid row="0" column="0" row-span="1" col-span="1" vsize-policy="7" hsize-policy="7" anchor="0" fill="3" indent="0" use-parent-layout="false"/>
                </constraints>
                <properties/>
                <border type="none"/>
                <children>
                  <component id="8217" class="com.intellij.ui.treeStructure.treetable.TreeTable" binding="tree" custom-create="true">
                    <constraints/>
                    <properties/>
                  </component>
                </children>
              </scrollpane>
            </children>
          </grid>
        </form>

And the code behinde (RegisterViewSessionTab):

        pc = new DefaultRegisterNode();
        sp = new DefaultRegisterNode();
        DefaultRegisterNode group = new DefaultRegisterNode();
    
        group.setName("Core Registers");
        group.setDescription("Core Registers");
        group.setValue("");
        DefaultMutableTreeNode root = new DefaultMutableTreeNode(group);
    
        pc.setName("PC");
        pc.setDescription("Program Counter [Core]");
        pc.setValue("---");
        DefaultMutableTreeNode nodePc = new DefaultMutableTreeNode(pc);
        root.add(nodePc);
    
        sp.setName("SP");
        sp.setDescription("Stack Pointer [Core]");
        sp.setValue("---");
    
        DefaultMutableTreeNode node = new DefaultMutableTreeNode(sp);
        root.add(node);
    
        ColumnInfo[] columnInfos = new ColumnInfo[3];
        columnInfos[0] = new ColumnInfo<DefaultMutableTreeNode, String>("Name") {
            @Nullable
            @Override
            public String valueOf(DefaultMutableTreeNode defaultRegisterNode) {
                return ((DefaultRegisterNode)defaultRegisterNode.getUserObject()).getName();
            }
        };
        columnInfos[1] = new TableModelEditor.EditableColumnInfo<DefaultMutableTreeNode, String>("Value") {
            @Nullable
            @Override
            public String valueOf(DefaultMutableTreeNode defaultRegisterNode) {
                return ((DefaultRegisterNode)defaultRegisterNode.getUserObject()).getValue();
            }
    
            @Nullable
            @Override
            public TableCellEditor getEditor(DefaultMutableTreeNode defaultRegisterNode) {
                return new StringTableCellEditor(project);
            }
    
            @Override
            public void setValue(DefaultMutableTreeNode defaultRegisterNode, String value) {
                ((DefaultRegisterNode)defaultRegisterNode.getUserObject()).setValue(value);
            }
        };
        columnInfos[2] = new ColumnInfo<DefaultMutableTreeNode, String>("Description") {
            @Nullable
            @Override
            public String valueOf(DefaultMutableTreeNode defaultRegisterNode) {
                return ((DefaultRegisterNode)defaultRegisterNode.getUserObject()).getDescription();
            }
        };
    
        ListTreeTableModelOnColumns registersModel = new ListTreeTableModelOnColumns(root, columnInfos);
        tree = new TreeTable(registersModel);

       

Model class:

    public class DefaultRegisterNode {
        private String name;
        private String description;
        private String value;
    
        public void setName(String name) {
            this.name = name;
        }
    
        public String getName() {
            return name;
        }
    
        public String getDescription() {
            return null;
        }
    
        public void setDescription(String description) {
            this.description = description;
        }
    
        public String getValue() {
            return value;
        }
    
        public void setValue(String value) {
            this.value = value;
        }
    }

In action:

But there isn't a collapsed/expanded button? How can I enable this feature in the TreeTable?

If you need something more, please contact me!
Thanks
