title: How do I center the text in the header row of an element-ui table?
body: <p>I tried centering the text in the header of my element-ui table via:</p>
  
  <pre><code>&lt;el-table :data="myTable" header-row-style="text-align: center;"&gt;
  </code></pre>
  
  <p>Unfortunately, that doesn't have the desired effect. How do I center the names of the columns?</p>
