Table inside Child do not save their column layout

[jpbrault]

Version/Branch of Dear ImGui:

Version: 1.78 WIP / 17703
Branch: table

Back-end/Renderer/Compiler/OS

Back-ends: imgui_impl_opengl2.cpp + imgui_impl_sdl.cpp

My Issue/Question:

I have a table inside a child block that I would like to have it column layout to be saved in the ini file.

  const auto footerHeight = ImGui::GetTextLineHeightWithSpacing() + 5.0f;
  if ( ImGui::BeginChild( "Child", ImVec2{ 0, - footerHeight } ) )
  {
    if ( ImGui::BeginTabBar( "TabBar" ) )
    {
      if ( ImGui::BeginTabItem( "Table" ) )
      {
        if ( ImGui::BeginTable( "Table", 2, ImGuiTableFlags_Reorderable | ImGuiTableFlags_Resizable, ImVec2{ 0, 0 } ) )
        {
          ImGui::TableSetupColumn( "Col1" );
          ImGui::TableSetupColumn( "Col2" );
          ImGui::TableAutoHeaders();
          ImGui::EndTable();
        }
        ImGui::EndTabItem();
      }
      if ( ImGui::BeginTabItem( "Not Table" ) )
      {
        ImGui::EndTabBar();
      }
      ImGui::EndTabItem();
    }
    ImGui::EndChild();
  }
  ImGui::Text("Footer");
  ImGui::End();

This is not working because the BeginChild have implicitly the ImGuiWindowFlags_NoSavedSettings.

Adding the following line after the BeginChild() work around the problem.

ImGui::GetCurrentWindow()->Flags &= ~ImGuiWindowFlags_NoSavedSettings;

Makes sense, thanks for pointing this out! I'll be looking for a solution for this (while keeping child window data themselves unsaved).

Pushed a fix for this, see 7bf78c6
Thanks for reporting!

(Fix reminds me I want to do some work on this RootWindow/RootWindowDockStop thing in docking branch.. )
