title: How do I auto-fit a row height after merging cells?
body: <p>I am generating a spreadsheet using:
  Rails 3.2.12 with the axlsx gem (version 2.0.0)</p>
  
  <p>There are cells which I want to have the text wrap and the height of the row adjust to match. This works when I use the following:</p>
  
  <pre><code>p = Axlsx::Package.new
  wb = p.workbook
  
  wb.styles do |s|
    wrap_text = s.add_style alignment: { wrap_text: true }
        wb.add_worksheet(name: "Sheet1") do |sheet|
          sheet.add_row [variable_containing_long_text], style: wrap_text
  </code></pre>
  
  <p>However, if I then merge that cell with others: Example
  <code>sheet.merge_cells("A14:C14")</code>
  the row height no longer auto-fits the contents.</p>
  
  <p>How do I get the auto-height for the row based on contents after merging the cells?</p>
