title: How to retrieve the page number we are currently on, while using an antd table
body: <p>I have created a table with the Antd in Reactjs. I have used 50 rows per page and I have around 6 pages that come up in the pagination.
  I have added an index column to the table, which loops from 1 to 50 on every page. 
  Rather I need it to loop from 1 to full length. So when I navigate to page 2, It must show 51 to 100, whereas in my case it loops from 1 to 50 again. I made use of "index",that is passed from the "render" function in the table.</p>
  
  <pre><code>function indexRenderer(text, record, index) {
      return index+1
  }
  </code></pre>
  
  <p>Is there any seperate function I can use to retrieve the page count alone from the pagination of antd.</p>
