title: SheetJS js-xlsx - SheetJS is auto formatting my column with percentage value
body: <p>I have the following HTML tables and Javascript function, using SheetJS to parse the tables then export them to an excel file.</p>
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>var tablesToExcel = (function() {
  
      return function(tables, wsnames, wbname) {
  
          var workbook = XLSX.utils.book_new();
  
          for (var i = 0; i &lt; tables.length; i++) {
              var ws1 = XLSX.utils.table_to_sheet(document.getElementById(tables[i]));
              console.log(ws1);
              XLSX.utils.book_append_sheet(workbook, ws1, wsnames[i]);
          }
          XLSX.writeFile(workbook, wbname);
      }
  })();</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;table id="po-table"&gt;
    &lt;thead class="thead-dark"&gt;
      &lt;tr&gt;
          &lt;th scope="col"&gt; Operating Unit&lt;/th&gt;
          &lt;th scope="col"&gt; Rate &lt;/th&gt;
      &lt;/tr&gt;
    &lt;/thead&gt;
    &lt;tbody&gt;
      &lt;tr&gt;
        &lt;td&gt;Leyte&lt;/td&gt;
        &lt;td&gt;90%&lt;/td&gt;
      &lt;/tr&gt;
    &lt;/tbody&gt;
  &lt;/table&gt;
  &lt;table id="cert-table"&gt;
    &lt;thead class="thead-dark"&gt;
      &lt;tr&gt;
          &lt;th scope="col"&gt; Operating Unit&lt;/th&gt;
          &lt;th scope="col"&gt; Rate &lt;/th&gt;
      &lt;/tr&gt;
    &lt;/thead&gt;
    &lt;tbody&gt;
      &lt;tr&gt;
        &lt;td&gt;Samar&lt;/td&gt;
        &lt;td&gt;100%&lt;/td&gt;
      &lt;/tr&gt;
    &lt;/tbody&gt;
  &lt;/table&gt;
  &lt;button onclick="tablesToExcel(['po-table', 'cert-table'], ['PO', 'Cert'], 'PO Report.xls')"  class="btn btn-success btn-lg mb-5" id="downloadTable" type="button"&gt; Export as Excel&lt;/button&gt;</code></pre>
  </div>
  </div>
  </p>
  <p>The expected output should display <strong>90%</strong> in the column but in reality, the result shown on the column from the generated excel file was <strong>0.9</strong>.</p>
  <p>Is there any way that I can format the columns or disable this auto formatting by SheetJS?</p>
