  <h1>
    HTML in Column Headers
  </h1>
  <p>
    FlexGrid columns have an <b>isContentHtml</b> property that determines
    whether the data bound to cells contains HTML rather than plain text/data.</p>
  <p>
    This property only applies to scrollable cells, though. If you want to
    show HTML in the grid's column headers, use the <b>formatItem</b> event
    and set the cells <b>innerHTML</b> property:</p>
  <div id="theGrid"></div>
</div>

CSS

.wj-flexgrid {
  margin: 12px;
