title: How to add event on click on ant design vue table column title?
body: <pre><code>const columns = [
    { title: 'Name', dataIndex: 'name', width: 300 
      onHeaderCell: column =&gt; {
        return {
          onClick: e =&gt; {
            this.customize(e);
          },
        };
      },},
    { title: 'Employee ID', dataIndex: 'displayId', width: 150 },
    { title: 'Normal', dataIndex: 'normal.name', width: 100 },
    { title: 'Overtime', dataIndex: 'overtime.name', width: 100 },
    { title: 'Holiday', dataIndex: 'holiday.name', width: 100 },
    { title: 'Rest Day', dataIndex: 'restDay.name', width: 100 },
  ];
  </code></pre>
  
  <p>I have an ant design vue table and want to add event on click to change the title name. But I can't add on click event and customize the column title. </p>
  
  <p>Is there any way to make this happen when click the column title will triggered a function?</p>
