```html
<div id="example1">
  <div id="example-preview">
    <div id="toggle-boxes">
      <br/>
      <input v-on:click="toggleReadOnly" checked id="readOnlyCheck" type="checkbox"/>
      <label for="readOnlyCheck"> Toggle <code>readOnly</code> for the entire table</label>
    </div>
    <br/>
    <hot-table ref="wrapper" :settings="hotSettings"></hot-table>
  </div>
  <div id="vuex-preview">
    <h4>Vuex store dump:</h4>
    <table></table>
  </div>
