SpreadJS 集算表中的addRelationship使用说明

Derrick.Jiao

  官网例子：
         //add order table
         var orderTable = dataManager.addTable("orderTable", {
            remote: {
                  read: {
                     url: baseApiUrl + "/Order"
                  }
            }
         });
         //add customer table
         var customerTable = dataManager.addTable("customerTable", {
            remote: {
                  read: {
                     url: baseApiUrl + "/Customer"
                  }
            }
         });
         //add relationship between order table and customer table
         dataManager.addRelationship(orderTable, "CustomerId", "customer", customerTable, "Id", "orders");

API说明：
addRelationship(sourceTable, sourceFieldName, sourceRelationshipName, targetTable, targetFieldName, targetRelationshipName)[color=gray !important][backcolor=transparent !important][size=0.7em]{Object}

将关系添加到数据管理器中

addRelationship函数中，customer，orders这两个sourceRelationshipName、targetRelationshipName参数是怎么定义的？请详细说明一下，在官网例子中可以找到customer，但是orders找不到 { value: "customer", width: 350, style: multiSelectStyle },
