Why does ImGui tables insert extra ID into the id path of the child widgets? about imgui

[ocornut]

When you call BeginTable() multiple times with the same, you create multiple instances of a same table (sharing settings, columns width) which needs a unique ID so e.g. headers, columns resize elements can be unique and function.
You can call PushOverrideID() with the previous instance ID if you like subsequent widgets to conflicts.

    ImGuiID table_id = ImGui::GetID("table");
    if (ImGui::BeginTable("table", 1)) {
        ImGui::PushOverrideID(table_id);
        ImGui::TableNextRow();
        ImGui::TableSetColumnIndex(0);
        ImGui::DragFloat("##drag-float", &value);  // .../table/0x8CD5DC7A [override]/##drag-float
        ImGui::PopID();
        ImGui::EndTable();
    }

Your request and explanation still sounds bizarre to me.
