如何处理<DataColumn>小部件的动态列表以避免Flutter DataTable小部件中的RenderFlex异常？

Widget buildDataTable(List<List<dynamic>> data) {
  return Expanded(
    child: ListView.builder(
      itemCount: data.length,
      itemBuilder: (context, index) {
        return DataTable(
          columns: _buildColumns(data[index].length),
          rows: _buildRows(data[index]),
        );
      },
    ),
  );
}

List<DataColumn> _buildColumns(int length) {
  return List.generate(
    length,
    (index) => DataColumn(
      label: Text('Column ${index + 1}'),
    ),
  );
}

List<DataRow> _buildRows(List<dynamic> rowData) {
  return [
    DataRow(
      cells: List.generate(
        rowData.length,
        (index) => DataCell(
          Text(rowData[index].toString()),
        ),
      ),
    ),
  ];
}
