可以通过写js实现

var a=this.options.form.getWidgetByName("td").getValue();

var chnNumChar = {

  零:0,

  一:1,

  二:2,

  三:3,

  四:4,

  五:5,

  六:6,

  七:7,

  八:8,

  九:9

};

var chnNameValue = {

  十:{value:10, secUnit:false},

  百:{value:100, secUnit:false},

  千:{value:1000, secUnit:false},

  万:{value:10000, secUnit:true},

  亿:{value:100000000, secUnit:true}

}

function ChineseToNumber(chnStr){

  var rtn = 0;

  var section = 0;

  var number = 0;

  var secUnit = false;

  var str = chnStr.split('');

  for(var i = 0; i < str.length; i++){

    var num = chnNumChar[str[i]];

    if(typeof num !== 'undefined'){

      number = num;

      if(i === str.length - 1){

        section += number;

      }

    }else{

      var unit = chnNameValue[str[i]].value;

      secUnit = chnNameValue[str[i]].secUnit;

      if(secUnit){

        section = (section + number) * unit;

        rtn += section;

        section = 0;

      }else{

        section += (number * unit);

      }

      number = 0;

    }

  }

  return rtn + section;

}

alert(ChineseToNumber(a));

还可以建个字典表

SWITCH(单元格,"十一","11","十二","12","十三","13")

要几个，就写几个了

还有替换的REPLACE(单元格,"十二","12")
