title: Font weight BOLD using formula in cell
body: <p>I'm using Google Spreadsheet to make some calculations.</p>
  
  <p>At the bottom of my table I need SUM, AVG and some others and everything is fine.</p>
  
  <p>But I made a long cell with all the text, like this:</p>
  
  <pre><code>="Hi at all, this is my report: "&amp;SUM(B:B)&amp;" are the sum of my fingers, "&amp;AVG(C:C)&amp;" is the avg of my sons."
  </code></pre>
  
  <p>and so on.</p>
  
  <p>Everything works. But I need to bold the <code>SUM(B:B)</code>.</p>
  
  <p>I won't use single cells for math results.</p>
  
  <p>I tried with <code>....&lt;b&gt;"&amp;SUM(B:B)&amp;"&lt;/b&gt;....</code> but obviously I take <code>&lt;b&gt;&lt;/b&gt;</code> in my cell and not the bold font weight.</p>
  
  <p>How to style from formula in cell?</p>
