Details:

My understanding is that groups should surround containing widgets, which isn't the case with tables.

Table surrounded by BeginGroup/EndGroup appears to be measured incorrectly.

Problem can be reproduced simply by resizing Test2 window. Green rect is expected to cover whole table.
Push shift key to enable workaround, which place 0 size dummy widget at the same line as table.

Digging into the code, table OuterRect seems to be "stuck" on minimum size. At the moment I cannot tell if this is an desired behavior or not.

Minimal, Complete and Verifiable Example code:

ImGui::Begin("Test2");
ImGui::BeginGroup();
if (ImGui::BeginTable("table2", 2))
{
    ImGui::TableNextColumn();
    ImGui::Text("Thing 1");
    ImGui::TableNextColumn();
    ImGui::Text("Thing 2");
    ImGui::EndTable();
}

if (ImGui::GetIO().KeyShift)
{
    ImGui::PushStyleVar(ImGuiStyleVar_FramePadding, ImVec2(0.0f, 0.0f));
    ImGui::SameLine(0.0f, 0.0f);
    ImGui::Dummy(ImVec2(0.0f, 0.0f));
    ImGui::PopStyleVar();
}
ImGui::EndGroup();
ImGui::GetWindowDrawList()->AddRectFilled(ImGui::GetItemRectMin(), ImGui::GetItemRectMax(), IM_COL32(0, 255, 0, 64), 4.0f);
ImGui::End();
