ImGui::BeginTable and ImGui::Separator() exceed the node boundaries

[Nanke2012]

These elements are not constrained by the node boundaries
void draw() override
{
ImGui::Text("ID:%d",mId);
ImGui::Separator();
if (ImGui::BeginTable("table", 2, ImGuiTableFlags_Borders | ImGuiTableFlags_RowBg)) {
ImGui::TableSetupColumn("Key");
ImGui::TableSetupColumn("Value");
ImGui::TableHeadersRow();
ImGui::TableNextRow();
ImGui::TableSetColumnIndex(0);
ImGui::TextWrapped("%s", "key1");
ImGui::TableSetColumnIndex(1);
ImGui::TextWrapped("%s", "value1");
ImGui::EndTable();
}
}

Have you tried removing ImGui::Separator();? I feel like that might be the one breaking everything
