title: React Ant Design Table - multiple (column) row selection
body: <p>Ant Design has a <code>rowSelection</code> <a href="https://ant.design/components/table/#components-table-demo-row-selection-and-operation" rel="nofollow noreferrer">feature</a> to use on their <code>&lt;Table /&gt;</code> element, and looks like so:

  <p>I don't see anywhere that would indicate a multi-column row selection, like so:

  <p>I've checked out <a href="https://github.com/ant-design/ant-design/issues/11404" rel="nofollow noreferrer">this</a> Github issue that I thought was asking the same thing, and <a href="https://github.com/ant-design/ant-design/commit/08e83193f2248e8c960bb66e760a1d850034bd50" rel="nofollow noreferrer">this</a> PR that supposedly addressed it, but I cannot figure out how it supposed to be used (perhaps I'm mistaken that it has been implemented).</p>
  
  <p>Is this currently possible to achieve using existing Ant Design code, or would something custom need to be implemented?</p>
  
  <p><strong>Version:</strong> We are using Ant Design 3.9.3</p>
