title: suppress "number stored as text" warning in Excel VSTO with C#
body: <p>I am working in a Excel VSTO project with C#. 
  For certain columns, I have set the NumberFormat to Text using </p>
  
  <pre><code>someCell.EntireColumn.NumberFormat = "@";
  </code></pre>
  
  <p>But when numbers do happen to be in these columns, Excel shows a green arrow with warning "Number Stored as Text". I want to suppress this warning message. </p>
  
  <p>I know how to do that in Excel: Options -> Formulas -> in Error checking rules, uncheck "Numbers formatted as text or preceded by an apostrophe". Is it possible to do this in C# code, and only to certain cells/ranges? Thanks! </p>
