<body align="center" onload="setup()"> <!--retirei o setup(), pois já faço uma chamada no js-->
        <h1>IMPEXPROS</h1>

        <div id="lista" class="table"> <!--inclui um id pra facilitar no js-->
          <div class="row-table-head">
            <div style="background-color:black; color:white; font-weight:bold" class="col-table">LISTA TODOS USUARIOS</div>
          </div>
        </div>
  </body>

As I do to get the element index, for example, when I press the delete button of the user Pedro, I know that he is the 2 of the list. just using js.

Victor, you want to delete visually only?

You can pass the client id pro id of the delete button, and then recover it in the delete function

Would look like this:

const setup = async() => {
  let teuarray = [];
  teuarray.push({id:"0",nome: "Vitor"}, {id:"1",nome: "Pedro"}, {id:"2",nome: "João"});

  const lista = document.getElementById('lista');

  teuarray.map((cliente)=> {
        let divRowT = document.createElement("div");
        divRowT.className = "row-table";
        let divDivT = document.createElement("div");
        divDivT.className = "div-table";

        let id = document.createElement("a");
        id.className = "col-table";
        id.href = "https://answall.com";
        let idValue = document.createElement("div");
        idValue.appendChild(document.createTextNode(cliente.id));
        id.appendChild(idValue);
        divDivT.appendChild(id);

        let nome = document.createElement("a");
        nome.className = "col-table";
        nome.href = "https://answall.com";
        let nomeValue = document.createElement("div");
        nomeValue.appendChild(document.createTextNode(cliente.nome));
        nome.appendChild(nomeValue);
        divDivT.appendChild(nome);

        let divColT = document.createElement("div");
        divColT.className = "col-table";
        let btnExcluir = document.createElement("input");
        btnExcluir.type = "button";
        btnExcluir.id = cliente.id; // no id do button eu passei o id do usuário
        btnExcluir.value = "Excluir";
        btnExcluir.addEventListener("click", excluir, false);
        divColT.appendChild(btnExcluir);
        divDivT.appendChild(divColT);

        divRowT.appendChild(divDivT);
        lista.appendChild(divRowT);
      });
      }
    
function excluir() 
{
  // var c = document.getElementById("excluirUsuario").childNodes;

  // console.log(c[0]);
  let btnSelecionado = event.currentTarget;
  let elementopai = btnSelecionado.parentElement;
  let elementopaidopai = elementopai.parentElement;
  elementopaidopai.remove();
  console.log(btnSelecionado.id);
}

.row-table-head, .div-table, .row-table{
    display: grid;
    grid-template-columns: 50px 180px 70px;
    width: 300px;
    margin: auto;
  }
  .row-table-head{
    display: block;
  }
  .row-table a{
    text-decoration: none;
    color: #000;
  }
  .div-table:hover{
    background-color: #a0a0a0;
  }
  .row-table-head .col-table{
    padding: 6px 8px;
    border: 1px solid #ccc;
  }
  .row-table .col-table{
   padding: 0px 6px;

  }
