Answer 1

不要按 ID 分组。按名称分组

不要按 id 分组。按名称分组

    SELECT 
    u.nome,
    ef.nome AS nome_etapa,
    count(l.id) AS quantidade
    FROM usuario u
        LEFT join lead l ON l.id_usuario = u.id
        LEFT JOIN etapa_funil ef ON ef.id = l.id_etapa
            where
                u.permissao = "2"
                    GROUP BY u.nome, ef.nome  <--GROUP BY nomes
                    ORDER BY u.nome, ef.nome ASC;
