title: Table selection
body: <p>The user can select any comb of cells from the table. How can I generate a LINQ request if I don’t know in advance how many cells the user will select?</p>
  
  <pre><code>db.P.Where(p =&gt; p.Date == "01.01.2000");
  db.P.Where(p =&gt; p.FirstName == "Vitaly");
  </code></pre>
  
  <p>For example, he will select a <strong>Date</strong> and the <strong>First Name</strong> it will look like this:

  <p>But if you choose a different combination or more cells?</p>
