<g:each var ="pb" in="${pBill}">
        <tr>
            <td>${pb[0].voucherDate}</td>
            <td>(PB)${pb[0].voucherNumber.voucherNumber}</td>

        </tr>
        <tr>
            <td>${pb[1].voucherDate}</td>
            <td>(PBR)${pb[1].voucherNumber.voucherNumber}</td>

    </g:each>

Either:

  • Flatten the original list to end up with one list to iterate over.

Example:

[[a,b],[c,d]].flatten() == [a, b, c, d]

and use one g:each.

OR

  • Iterate over the 2d array twice.

example:

<g:each var="elem" in="${mainList}">
    <g:each var="item" in="${elem}">
        <!-- Create the tabular structure -->
    </g:each>
</g:each>
