title: Table detection using tesseract api
body: <p>Is there any way using tesseract ocr detect tables.</p>
  
  <p>I am using the following c# code (charlesw/tesseract)</p>
  
  <pre><code>using (var iter = page.GetIterator())
  {
      iter.Begin();
      do
      {
          var blockType = iter.BlockType; // Never equals to Table
  
      } while (iter.Next(PageIteratorLevel.Word));
  }
  </code></pre>
  
  <p>Iterating over blocks and querying <code>BlockType</code> property, but it never returns <code>PolyBlockType.Table</code> value, even if I had table in my document</p>
  
  <p>I have also tried to set "textord_tabfind_find_tables" variable to true, but no luck.</p>
