title: Fixed table header and height in Material-UI@next (v1.0.0-beta.8)
body: <p>In Material-UI@v0.xx.x there are props for table height and fixed table header, but unfortunately they don't seem to be implemented in Material-UI@next. Is there a workaround in order to achieve the same thing using Material-UI@next?</p>
  
  <p>I've tried switching to v0.19.1 and rebuilt my table component using that version, but this leaves me with a new bug regarding multiselect (<a href="https://github.com/callemall/material-ui/issues/5964" rel="noreferrer">https://github.com/callemall/material-ui/issues/5964</a>).</p>
  
  <p>Any suggestions on how to solve either of these issues?</p>
