[Vuejs]-Add v-html attribute only if slot not given

You can place default value if slot is not given –
Fallback-Content

How about this:

1 <td v-for="col in cols">
2  <slot :name="col.bSlot" :row="row">
3     {{ formatField(row, col) }}
4     // <-- this is a comment
5     // <span v-html="formatField(row, col)"></span>
6   </slot>
7 </td>
