Method TableDrawDefaultContextMenu

include/imgui/imgui_tables.cpp:3569–3680

Output context menu into current window (generally a popup) FIXME-TABLE: Ideally this should be writable by the user. Full programmatic access to that data? Sections to display are pulled from 'flags_for_section_to_display', which is typically == table->Flags. - ImGuiTableFlags_Resizable -> display Sizing menu items - ImGuiTableFlags_Reorderable -> display "Reset Order" /- ImGuiTableFlags_Sortab

// - ImGuiTableFlags_Hideable    -> display columns visibility menu items
// It means if you have a custom context menus you can call this section and omit some sections, and add your own.
