My Issue/Question:

Hello! I have a table where a column is a check that tints into red or green. So I just found myself in a situation where the cell background color is drawn above the fixed header when I scroll.

So far my code simply creates the table, defines the columns then fill the cells with a particular color:

if (ImGui::BeginTable("##Table", 6, TableFlags))
{
	ImGui::SetWindowFontScale(1.3);
	ImGui::TableSetupColumn("Game", ImGuiTableColumnFlags_WidthFixed, Size.x * 0.2f);
	ImGui::TableSetupColumn("LoadJson", ImGuiTableColumnFlags_WidthFixed, Size.x * 0.05f);
	ImGui::TableSetupColumn("LGM", ImGuiTableColumnFlags_WidthFixed, Size.x * 0.05f);
	ImGui::TableSetupColumn("FastTest", ImGuiTableColumnFlags_WidthFixed, Size.x * 0.05f);
	ImGui::TableSetupColumn("Consumer", ImGuiTableColumnFlags_WidthFixed, Size.x * 0.05f);
	ImGui::TableSetupColumn("Error", ImGuiTableColumnFlags_WidthStretch);
	ImGui::TableSetupScrollFreeze(0, 1);
	ImGui::TableHeadersRow();
	ImGui::SetWindowFontScale(1);

	for (auto& File : std::filesystem::directory_iterator(Settings::DefaultSlotsDefinitionPath))
	{
		RenderItem(File.path());
	}

	ImGui::EndTable();
}

RenderItem():

ImGui::TableNextRow();
ImGui::TableNextColumn();
ImGui::Text("%s", File.filename().c_str());
ImGui::TableNextColumn();
ImGui::TableSetBgColor(ImGuiTableBgTarget_CellBg, ImGui::ColorConvertFloat4ToU32(ImVec4(.9, .0, .0, .5)));
ImGui::SetCursorPosX(ImGui::GetCursorPosX() + ImGui::GetColumnWidth() / 2 - 10);
ImGui::Text(ICON_MD_CHECK);
ImGui::TableNextColumn();
...

On the rest of the code I have some styling elements like changing the padding, etc.. that I decided not to copy so I keep this post from being too large. Header color alpha thought is 100% so I don't think that's the problem.
