Does anyone know the best language to do this search, I want to click the value and get the value of the product, the city, and the price and put it in the panel just below? 

table{ border-collapse: collapse !important; }
table tr td input{ width: 100%; border: none; background-color: #fff; }
table tr td input:hover{ width: 100%; border: none; background-color: #E7E9E8; cursor: pointer; }
section legend{ border-bottom: 1px solid #000; width: 55%; margin-bottom: 10px; }
section article{ width: 40%; background-color: #CC6F23; margin: 10px; padding: 10px;}
section article p{ margin: 0px; font-weight: bold; color: #fff; }
<table border="1" id="table">
      <tr class="cabecalho">
          <th class="not">ESTOQUE <br/><span>Produto / Preço / Cidade</span></th>
          <th class="coluna">Cidade 01</th>

You can do it like this: 

var article = getElements('article p span');

function getElements(selector, rel) {
    var list = (rel || document).querySelectorAll(selector);
    return [].slice.call(list);
}

function handler(el, indexTr, indexTd) {
    return function(e) {
        var cidade = cols[indexTd].innerHTML;
        var produto = linhas[indexTr].querySelector('th').innerHTML;
        var preco = el.innerHTML;

        [cidade, produto, preco].forEach(function(val, i) {
            article[i].innerHTML = val;
        });
    }
}

var cols = getElements('th').slice(1);
var linhas = getElements('tr').slice(1);
linhas.forEach(function(tr, i) {
    var tds = getElements('td', tr);
    tds.forEach(function(td, j) {
        td.addEventListener('click', handler(td, i, j));
    });
});

Separating into three parts:

  • Arrange elements into groups for later use
  • scroll through td and add event headers that hold row and column number
  • fetch the data and distribute it in the results fields

If you need more help to understand the code I'll give you a clarification tomorrow. Today was what gave. Good luck.
