Answer 1

You probably want something like:
<div th:if="${not #lists.isEmpty(stateToDistrictMap)}">
<table>
<tr>
<td>State</td>
<td>Districts</td>
</tr>
<th:block th:each="state: ${stateToDistrictMap}">
<tr th:each="district, i: ${state.value}">
<td th:text="${i.first ? state.key : ' '}" />
<td th:text="${district.name}" />
<td th:text="${district.code}" />
<td th:text="${district.erstyear}" />
<td th:text="${district.info}" />
</tr>
</th:block>
</table>
</div>
