title: EPPlus isn't honoring ExcelHorizontalAlignment Center or Right
body: <p>I've tried this in EPPlus versions 3.1.3.0 and the latest 4.0.4.0 and both are exhibiting the same behavior.</p>
  
  <p>I'm trying to Center align text in cells but it's just not working. Numbers in cells work fine, strings do not. Following is an example of code that fails to produce the desired ExcelHorizontalAlignment:</p>
  
  <pre><code>var newFile = new FileInfo(@"C:\Temp\sample.xlsx");
  using (var package = new ExcelPackage(newFile))
  {
      var workSheet = package.Workbook.Worksheets.Add("Content");
  
      workSheet.Column(1).Width = 50;
  
      workSheet.Cells["A1"].Value = "This should be left-aligned";
      workSheet.Cells["A1"].Style.HorizontalAlignment = ExcelHorizontalAlignment.Left;
  
  
      workSheet.Cells["A2"].Value = "This should be center-aligned";
      workSheet.Cells["A2"].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;      // &lt;- This  doesn't work.
  
      workSheet.Cells["A3"].RichText.Add("This should be center-aligned");
      workSheet.Cells["A3"].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;      // &lt;- This  doesn't work.
  
  
      workSheet.Cells["A4"].Value = "This should be right-aligned";
      workSheet.Cells["A4"].Style.HorizontalAlignment = ExcelHorizontalAlignment.Right;       // &lt;- This  doesn't work.
  
      workSheet.Cells["A5"].RichText.Add("This should be right-aligned");
      workSheet.Cells["A5"].Style.HorizontalAlignment = ExcelHorizontalAlignment.Right;       // &lt;- This  doesn't work.
  
  
      //workSheet.Cells["A2:A3"].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center; // &lt;- This  doesn't work.
      //workSheet.Cells["A4:A5"].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center; // &lt;- This  doesn't work.
  
      package.Save();
  }
  </code></pre>
  
  <p>It's making me a little  crazy. Any ideas why strings cannot be aligned?</p>
