title: A checkbox data type and showing more than one row per "row" (in Adazzle react-data-grid)
body: <p>We'd like to use React Data Grid from Adazzle (as mentioned in the tag with this question) now that we're using React (16.xx) and the older jsGrid is less appealing. </p>
  
  <p>Two questions: </p>
  
  <ol>
  <li><p>Our old jsGrid had a data type to include in the grid called Checkbox. This was immensely helpful. I haven't found a similar type in the React Grid. Have I just missed it or is it not a part of the library?</p></li>
  <li><p>In each row, in some columns, we'd like to actually have two rows of data inside the column -- i.e., two lines of text separated by carriage return. But the react-data-grid demos only seem to show one line per column. Is this a limitation, or can we use CSS in the values inside columns?</p></li>
  <li><p>Is there search included for the rows shown in the table at any given point in time? </p></li>
  </ol>
