bootstrap-table 合并单元格方法

前面的话

  最近做一个表格需要根据前边列的字段合并之后列的相同字段单元格，网上找到的都是ji基于单个列字段重复次数的合并，所以自己写了一个。

这是基于单个列字段合并的有错误的表格。

这个是正常的

定义表格

    //表格列定义
    var columnlist=[
        {field:"GDSTITLE",title:"乡镇"},
        {field:"NAME2",title:"一级专项",formatter:function (value,row,index) {
                return ''+value+''
            }},
        {field:"NAME1",title:"二级专项",formatter:function (value,row,index) {
                return ''+value+''
            }},
        {field:"CATALOGNAME",title:"三级专项",formatter:function (value,row,index) {
                return ''+value+''
            }},
        {field:"NUM",title:"数量(个)"},
        {field:"AREA",title:"面积(公顷)"}
    ];
    //表格参数
    var tableParams={
        data: data,
        sidePagination: "client",
        showFooter: false,
        showHeader: true,
        checkboxHeader: true,
        pagination: false, //是否显示分页（*）
        columns:columnlist,
        onClickCell: function(field, value, row, $cell) {
        },
        formatNoMatches: function() {
            return "对不起，没有查询到相关的数据...";
        },
        formatLoadingMessage: function() {
            return "请稍等，数据正在加载中...";
        }
    }
    $("#table").bootstrapTable(tableParams);

        mergeCells(data, "GDSTITLE", 1, $("#table")[0],[]);
        mergeCells(data, "NAME2", 1, $("#table")[0],["GDSTITLE"])
        mergeCells(data, "NAME1", 1, $("#table")[0],["GDSTITLE","NAME2"])
        mergeCells(data, "CATALOGNAME", 1, $("#table")[0],["GDSTITLE","NAME2","NAME1"]);

合并方法

/**
 * 合并行
 * @param data  原始数据（应在服务端完成排序）
 * @param fieldName 合并属性名称数组
 * @param colspan 列数
 * @param target 目标表格对象
 * @param upperLevelFieldname 该字段上一级的字段集合（合并格数不能超过上一字段）
 */
function mergeCells(data, fieldName, colspan, target,upperLevelFieldnameList) {
    if (data.length == 0) {
        return;
    }
    //初始化upperFieldValueList
    var upperFieldValueList=[];
    upperLevelFieldnameList.forEach(function (item) {
        upperFieldValueList.push(data[0][item]);
    })
    data.push({"GDSTITLE":"","NAME2":"","NAME1":"","CATALOGNAME":""});//主要是给数据增加一行解决底部合并问题
    var numArr = [];
    var value = data[0][fieldName];
    var num = 0;
    for (var i = 0; i < data.length; i++) {debugger
        if ((value != data[i][fieldName])|doCheck(data[i],upperLevelFieldnameList)) {
            numArr.push(num);
            value = data[i][fieldName];
            num = 1;
            continue;
        }
        num++;
    }
    var merIndex = 0;
    for (var i = 0; i < numArr.length; i++) {
        $(target).bootstrapTable('mergeCells', { index: merIndex, field: fieldName, colspan: colspan, rowspan: numArr[i] })
        merIndex += numArr[i];
    }

    //用于检查是否相同，相同返回false不相同更新父类并返回true
    function doCheck(item,upperLevelFieldnameList) {
        var log=false;
        upperLevelFieldnameList.forEach(function (value,index) {
            if(upperFieldValueList[index] !=item[value]){
                log=true;
                upperFieldValueList[index]=item[value]
            };
        })
        return log;
    }
}
