I have a requirements to create dynamic table on the basis of array type columns in my data. Both array type column have the same number of attributes.

Here Column D AND E which I pointed in my dataset are array type columns.

{{#each data}}
    <table>
        <tr>
            <th>REG</th>
            <th>TYPE</th>
            <th>STO</th>
            {{#each D}}
                <th>{{this}}% </th>
            {{/each}}
        </tr>
        <tr>
            <td>{{A}}</td>
            <td>{{B}}</td>
            <td>{{C}}</td>
            {{#each E}}
                <td>{{this}}</td>
            {{/each}}
        </tr>
    </table>
{{/each}}

I was expecting it create dynamic header in table HTML attribute, but it did not create anything, if I just reference D and E, it shows be array data in square bracket.
