[park365]

Describe the bug

I want to make the react-data-grid fit a div with flex layout. In this layout, drag window, react-data-grid could resize follow the window and colud show horizon/vertical bar.

To Reproduce

Look at this demo:
https://codesandbox.io/s/exciting-jerry-50ygp1?file=/src/App.js:4645-5199

1. middle is a flex:1 div
2. fill-grid:
   a. set block-size: 100% will fill window height, but it will cover othe div like top/bottom in the example
   b. when i set fixed height , react-data-grid display as i expected, but this i should manual calculate div height.

Link to code example:
