Method TableSetColumnEnabled

include/imgui/imgui_tables.cpp:1777–1788

Change user accessible enabled/disabled state of a column (often perceived as "showing/hiding" from users point of view) Note that end-user can use the context menu to change this themselves (right-click in headers, or right-click in columns body with ImGuiTableFlags_ContextMenuInBody) - Require table to have the ImGuiTableFlags_Hideable flag because we are manipulating user accessible state. - Re

// - For the getter you can test (TableGetColumnFlags() & ImGuiTableColumnFlags_IsEnabled) != 0.
// - Alternative: the ImGuiTableColumnFlags_Disabled is an overriding/master disable flag which will also hide the column from context menu.
void ImGui::TableSetColumnEnabled(int column_n, bool enabled)

    ImGuiTable* table = g.CurrentTable;
