根据提供的规格数据（Map＜规格名称，List＜规格值＞＞），实现生成规格商品

规格数量可以随意添加（比如由颜色，尺码，改变成颜色，尺码，材质），按照顺序，同一规格项的数据自动合并单元格，简单的实现逻辑如下

补充个效果图：

function createTable(){
			//获取生成表格需要的数据
			// alert("获取规格信息");
			var checkSpList = [];
			//规格项数据
			var specData=changeDate(checkSpList);
			//获取门店数据
			var shopData="";
			if($("#shopId").val()!=null && $("#shopId").val().length>0){
				//说明是超市
				shopDataArr=$("#shopId").val();
				$(shopDataArr).each(function(index,ele){
					shopData+=ele+",";
				});
				shopData=shopData.substring(0,shopData.length-1);

			}else{
				//说明非超市
				//判断是否有选中的门店
				if($("#shopSel").val()!=null && $("#shopSel").val()!=''){
					shopData=$("#shopSel option:selected").text()+":"+$("#shopSel").val();
				}

			}


			//开始生成表格
			var specInfoTable=$("#specInfo-table");

			//选择的规格名称
			var checkSpName = [];
			if(checkSpList.length>0){
				$(checkSpList).each(function(index,element){
					$("input[name='specId']").each(function(index,ele){
						var specId=$(ele).val();
						if(specId==element){
							var specNmae=$(ele).attr("specNmae");
							checkSpName.push(specNmae);
						}


					});
				});
			}

			if(shopData!=""){
				specData.push(shopData);
				checkSpName.push("参与门店");
			}
			if(specData.length==0){
				specInfoTable.children().remove();
				return ;
			}

			//计算第n个规格需要跨几列

			console.error(categoryName);
			//开始循环生成表格

			}
			specInfoTable.html(html);
		}

其中getRows（）方法如下

function getRowsNum(specData){
			var rowsNum=[];
			var len=$(specData).length;
			var row1=1;
			for (let i = 0; i < len; i++) {
				var item=specData[i].split(',').length;
				row1*=item;
			}
			for (let i = 0; i < len; i++) {
				var item=specData[i].split(',').length;
				if(i==0){
					rowsNum[i]=row1/item;
				}else{
					rowsNum[i]=rowsNum[i-1]/item;
				}


				row1*=item;
			}
			return rowsNum;

		}

新增java实现根据提供的规格数据，实现生成规格商品

public R createTableData(String tenantId,String specId,String gName) {
        List<String> result=new ArrayList<>();
        Map<String,List<String>> map=new HashMap<>();
        map.put("颜色",Arrays.asList(new String[]{"赤","橙","黄","绿"}));
        map.put("大小",Arrays.asList(new String[]{"65","66","67","68"}));
        map.put("内存",Arrays.asList(new String[]{"128","256"}));
        map.put("版本",Arrays.asList(new String[]{"pro","plus"}));
        map.put("材质",Arrays.asList(new String[]{"k99"}));

        //选择的规格名称
        List<String> spec=new ArrayList<>();
        if(map.keySet().size()>0){
            StringBuilder sb=new StringBuilder("");
            for (String s : map.keySet()) {
                spec.add(s);
            }
        }
        //每个规格的步长
        int[] rowsNum=getRowNum(spec,map);
        int totalRows=rowsNum[0]*(map.get(spec.get(0)).size());
        for (int i = 0; i < totalRows; i++) {
            StringBuilder sb=new StringBuilder();
            for (int j = 0; j < spec.size(); j++) {
                int times=(int)(Math.floor(i/rowsNum[j]));
                int index=times%(map.get(spec.get(j)).size());
               sb.append(map.get(spec.get(j)).get(index));
            }
            String s = sb.substring(0, sb.length() - 1).toString();
            result.add(s);
        }
        return  R.data(result);
    }
private int[] getRowNum(List<String> spec,Map<String, List<String>> map) {
        int[] rowsNum=new int[spec.size()];
        int len=spec.size();
        int row1=1;
        for (int i = 0; i < len; i++) {
            int item=map.get(spec.get(i)).size();
            row1*=item;
        }
        for (int i = 0; i < len; i++) {
            int item=map.get(spec.get(i)).size();
            if(i==0){
                rowsNum[i]=row1/item;
            }else{
                rowsNum[i]=rowsNum[i-1]/item;
            }


            row1*=item;
        }
        return rowsNum;

    }
