Branch: latest docking + tables merged
Back-ends: imgui_impl_allegro5.cpp
Operating System: ubuntu 20.04 Linux

See code sample.
Hovering works fine, but if you click on the checkbox in the 2nd column of the table,
instead it expands the 1st column's width. Adding a label seems to fix the bug as work-around.
Cheers

void
show_bug()
{
    ImGui::SetNextWindowSize(ImVec2(400, 200), ImGuiCond_Always);

    bool window_visible = true;
    if (ImGui::Begin("MyWindow", &window_visible))
    {

        static ImGuiTableFlags flags = ImGuiTableFlags_BordersV | ImGuiTableFlags_BordersHOuter | ImGuiTableFlags_Resizable | ImGuiTableFlags_RowBg;

        if (ImGui::BeginTable("##Table", 2, flags))
        {
            ImGui::TableNextRow();

            ImGui::LabelText("", "checkbox");

            ImGui::TableNextCell();

            static bool mybool=0;
            ImGui::Checkbox("", &mybool);
            // ImGui::Checkbox(" ", &mybool);   // FIX: adding a label fixes the bug
            ImGui::TableNextRow();

            ImGui::EndTable();
        }

        ImGui::End();
    }
}
