1.思路

1>数据序列化。整理出同字段值并列行的数据格式。如：
[{name: wang}, {name: wang}, {name:fu}, {name: fu}]
2>计算同字段值并列行的个数数组。如：
[2, 2]
3>利用bootstrapTable自带的mergeCells方法进行合并。如
$(target).bootstrapTable('mergeCells',{index:index, field:fieldName, colspan: colspan, rowspan: count});

2.代码

mergeCells(TBArr,"name", "name", 1, $('#dt-table'))
function mergeCells(data,name,fieldName,colspan,target){
     //声明一个map计算相同属性值在data对象出现的次数和
     var sortMap = {};
     for(var i = 0 ; i < data.length ; i++){
         for(var prop in data[i]){
             if(prop == name){
                 var key = data[i][prop]
                 if(sortMap.hasOwnProperty(key)){
                     sortMap[key] = sortMap[key] * 1 + 1;
                 } else {
                     sortMap[key] = 1;
                 }
                 break;
             }
         }
     }
     var index = 0;
     for(var prop in sortMap){
         var count = sortMap[prop] * 1;
         $(target).bootstrapTable('mergeCells',{index:index, field:fieldName, colspan: colspan, rowspan: count});
         index += count;
     }
 }
