Filter in a Table

[MarcuzziGiuseppe]

Hi, I would like to be able to filter in a table but I can't understand how to connect the 2 things.
This is my table and I would not like to change it if possible:

Thanks to any help.

int selectedRow = -1;
static ImGuiTableFlags flags = ImGuiTableFlags_SizingFixedFit | ImGuiTableFlags_RowBg | ImGuiTableFlags_Borders | ImGuiTableFlags_Resizable | ImGuiTableFlags_Reorderable;
if (ImGui::BeginTable("table1", 3, flags)) {
ImGui::TableSetupColumn("ID", ImGuiTableColumnFlags_WidthFixed);
ImGui::TableSetupColumn("MARCA", ImGuiTableColumnFlags_WidthFixed);
ImGui::TableSetupColumn("DESCRIZIONE", ImGuiTableColumnFlags_WidthStretch);
ImGui::TableHeadersRow();
for (int i = 0; i < pompeDisponibili.size(); i++) {
string testo = std::to_string(pompeDisponibili.at(i)->getId());
ImGui::TableNextRow();
ImGui::TableNextColumn();
if (ImGui::Selectable(testo.c_str(), selectedRow == i, ImGuiSelectableFlags_SpanAllColumns)) {
selectedRow = i;
}
testo = pompeDisponibili.at(i)->getMarca();
ImGui::TableNextColumn();
ImGui::Text(testo.c_str());
ImGui::TableNextColumn();
testo = pompeDisponibili.at(i)->getDescription();
ImGui::Text(testo.c_str());
}
}
ImGui::EndTable();
