使DataTable在Flutter中滚动双向

Question

如何使DataTable滚动双向。我使数据表滚动水平，但我的列表很大，无法向下滚动。

@override 
Widget build(BuildContext context) { 
    return Scaffold(
      appBar: AppBar(title: Text("Bills Receivable"),),
      body:SingleChildScrollView( 
        scrollDirection: Axis.horizontal, 
        child:
           DataTable(
          columns: <DataColumn>[
            DataColumn(label:Text("BNm",style: TextStyle(fontWeight: FontWeight.bold),)),
            DataColumn(label:Text("BDt",style: TextStyle(fontWeight: FontWeight.bold),)),
            DataColumn(label:Text("BPrty",style: TextStyle(fontWeight: FontWeight.bold),)),
            DataColumn(label:Text("BdueDt",style: TextStyle(fontWeight: FontWeight.bold),)),
            DataColumn(label:Text("Dys",style: TextStyle(fontWeight: FontWeight.bold),)),
            DataColumn(label:Text("BAmt",style: TextStyle(fontWeight: FontWeight.bold),)),
            DataColumn(label:Text("BPAmt",style: TextStyle(fontWeight: FontWeight.bold),)),
            DataColumn(label:Text("BBAmt",style: TextStyle(fontWeight: FontWeight.bold),))
          ], rows:  widget.rdata.bRecDtl.map((e)=>
            DataRow(
              cells:<DataCell>[
                DataCell(Text(e.bNm.toString())),
                DataCell(Text(e.bDt.toString())),
                DataCell(Text(e.bPrty.toString())),
                DataCell(Text(e.bdueDt.toString())),
                DataCell(Text(e.dys.toString())), 
                DataCell(Text(e.bAmt.toString())),
                DataCell(Text(e.bPAmt.toString())),
                DataCell(Text(e.bBAmt.toString())),
          ])).toList()
        ),
      ),
    );
  }

需要帮助。提前致谢。
