1、行合并想要的样式如下，需要合并4列的行，如下图（数据为模拟数据，如有雷同，纯属人品爆发）
##controller代码：
// 计算计划类型的合并的planRowSpan
int tiefaRowSpan = Integer.parseInt(String.valueOf(statisticsTieFaConList.size()));
int tiedaoRowSpan = Integer.parseInt(String.valueOf(statisticsTieDaoConList.size()));
// 客户所在位置下标
int logFlag = 0;
// 客户名称1,是判断标准
String logName1 = "";
// 客户名称2，随着循环变化
String logName2 = "";
// 客户的合并的行数
int logRowSpan = 1;
// 供应商所在位置下标
int supFlag = 0;
// 供应商名称1,是判断标准
String supName1 = "";
// 供应商名称2，随着循环变化
String supName2 = "";
// 供应商的合并的行数
int supRowSpan = 1;
// 货票号所在位置下标
int cargoFlag = 0;
// 货票号1,是判断标准
String cargoName1 = "";
// 货票号2，随着循环变化
String cargoName2 = "";
// 货票号的合并的行数
int cargoRowSpan = 1;
// 计算行的合并的rowspan的值 1、planRowSpan:计划类型，2、logRowSpan:客户公司，3、supRowSpan：运输公司，4、cargoRowSpan:货票号
for (int i=0; i < resultList.size(); i++) {
// 因为铁发和铁到是按照类别分开的，所以按照铁发的数量进行判断的分割

"ordering" : false,
// 按照最新下发的订单，订单编码是升序的排列顺序
// order: [[ 5, "desc" ]],
columnDefs: [{
targets: [0,1,2,3], //第1，2，3列
createdCell: function (td, cellData, rowData, row, col) {
