title: Laravel Excel export not including float values of 0.00
body: <p>I am exporting to excel using &quot;maatwebsite/excel&quot;: &quot;^3.1&quot;, but when I export, columns with values 0 or 0.0 are ignored and the cell is left empty.
  sample code:</p>
  <pre><code>public function array(): array
  {
      return $this-&gt;data;
  }
  
  public function columnFormats(): array
  {
      return [
          'C' =&gt; NumberFormat::FORMAT_TEXT,
          'E' =&gt; '0.00',
          'F' =&gt; '0.00',
          'G' =&gt; '0.00'
      ];
  }
  
  public function map($rows): array
  {
      return [
          $rows['employeeNumber'],
          $rows['basicSalary'],
          $rows['totalAllowance'],
          $rows['grossSalary']
      ];
  }
  </code></pre>
  <p>when values for the columns are 0 or 0.00, nothing is inserted in the cell.
