How to make nest rows in table via treenode.

I need something like treeview table already done in imgui c/c++ but i cannot implement it in python. can you please have a demo on how to do the similar in python ? The code snippet can be found in imgui_demo.cpp

**Necessary Assets**

` if (ImGui::TreeNode("Tree view"))
{
static ImGuiTableFlags flags = ImGuiTableFlags_BordersV | ImGuiTableFlags_BordersOuterH | ImGuiTableFlags_Resizable | ImGuiTableFlags_RowBg | ImGuiTableFlags_NoBordersInBody;

if (ImGui::BeginTable("3ways", 3, flags))
{
// The first column will use the default _WidthStretch when ScrollX is Off and _WidthFixed when ScrollX is On
ImGui::TableSetupColumn("Name", ImGuiTableColumnFlags_NoHide);
ImGui::TableSetupColumn("Size", ImGuiTableColumnFlags_WidthFixed, TEXT_BASE_WIDTH * 12.0f);
ImGui::TableSetupColumn("Type", ImGuiTableColumnFlags_WidthFixed, TEXT_BASE_WIDTH * 18.0f);
ImGui::TableHeadersRow();

// Simple storage to output a dummy file-system.
struct MyTreeNode
{
const char* Name;
const char* Type;
int Size;
int ChildIdx;
int ChildCount;
static void DisplayNode(const MyTreeNode* node, const MyTreeNode* all_nodes)
{
ImGui::TableNextRow();
ImGui::TableNextColumn();
const bool is_folder = (node->ChildCount > 0);
if (is_folder)
{
bool open = ImGui::TreeNodeEx(node->Name, ImGuiTreeNodeFlags_SpanFullWidth);
ImGui::TableNextColumn();
ImGui::TextDisabled("--");
ImGui::TableNextColumn();
ImGui::TextUnformatted(node->Type);
if (open)
{
for (int child_n = 0; child_n < node->ChildCount; child_n++)
DisplayNode(&all_nodes[node->ChildIdx + child_n], all_nodes);
ImGui::TreePop();
}
}
else
{
ImGui::TreeNodeEx(node->Name, ImGuiTreeNodeFlags_Leaf | ImGuiTreeNodeFlags_Bullet | ImGuiTreeNodeFlags_NoTreePushOnOpen | ImGuiTreeNodeFlags_SpanFullWidth);
ImGui::TableNextColumn();
ImGui::Text("%d", node->Size);
ImGui::TableNextColumn();
ImGui::TextUnformatted(node->Type);
}
}
};
static const MyTreeNode nodes[] =
{
{ "Root", "Folder", -1, 1, 3 }, // 0
{ "Music", "Folder", -1, 4, 2 }, // 1
{ "Textures", "Folder", -1, 6, 3 }, // 2
{ "desktop.ini", "System file", 1024, -1,-1 }, // 3
{ "File1_a.wav", "Audio file", 123000, -1,-1 }, // 4
{ "File1_b.wav", "Audio file", 456000, -1,-1 }, // 5
{ "Image001.png", "Image file", 203128, -1,-1 }, // 6
{ "Copy of Image001.png", "Image file", 203256, -1,-1 }, // 7
{ "Copy of Image001 (Final2).png","Image file", 203512, -1,-1 }, // 8
};

MyTreeNode::DisplayNode(&nodes[0], nodes);

ImGui::EndTable();
}
ImGui::TreePop();
}`
