特殊规则注意 > 设置动态单元格类型 > 当数据不完整时系统默认会进行补0操作便于小计表达式计算，如果该单元格不是数值类型则需要设置为文本，设置文本后该单元格显示为空；如：`备注`字段为空时，不需要展示为0，则设置备注字段类型为`文本`。 >  ## 数据格式 重要！！！(数据必须完整) > 特别注意：当有横向分组时，数据中第一条`数据必须完整`；例如：期望展示1-12月的数据，则第一条数据1-12月必须都有数据。 * SQL数据：  * 返回JSON格式： ~~~ { "data": [{ "amount": "100", "month": "1", "areaname": "华北", "year": "2020", "price": "5", "id": "1", "dept": "河北", "settleamount": "100" }, { "amount": "200", "month": "2", "areaname": "华北", "year": "2020", "price": "5", "id": "10", "dept": "河北", "settleamount": "200" }, { "amount": "202", "month": "2", "areaname": "华北", "year": "2020", "price": "6", "id": "12", "dept": "河南", "settleamount": "202" }, { "amount": "203", "month": "1", "areaname": "华东", "year": "2020", "price": "6", "id": "13", "dept": "辽宁", "settleamount": "203" }, { "amount": "204", "month": "2", "areaname": "华东", "year": "2020", "price": "6", "id": "14", "dept": "辽宁", "settleamount": "204" }, { "amount": "205", "month": "1", "areaname": "华南", "year": "2020", "price": "5", "id": "15", "dept": "湖北", "settleamount": "205" }, { "amount": "206", "month": "2", "areaname": "华南", "year": "2020", "price": "5", "id": "16", "dept": "湖北", "settleamount": "206" }, { "amount": "207", "month": "1", "areaname": "华南", "year": "2020", "price": "5", "id": "17", "dept": "安徽", "settleamount": "207" }, { "amount": "208", "month": "2", "areaname": "华南", "year": "2020", "price": "5", "id": "18", "dept": "安徽", "settleamount": "208" }, { "amount": "201", "month": "2", "areaname": "华北", "year": "2021", "price": "5", "id": "20", "dept": "河北", "settleamount": "201" }, { "amount": "200", "month": "1", "areaname": "华北", "year": "2021", "price": "5", "id": "21", "dept": "河北", "settleamount": "200" }, { "amount": "202", "month": "2", "areaname": "华北", "year": "2021", "price": "6", "id": "22", "dept": "河南", "settleamount": "202" }, { "amount": "209", "month": "1", "areaname": "华北", "year": "2021", "price": "6", "id": "23", "dept": "河南", "settleamount": "209" }, { "amount": "202", "month": "1", "areaname": "华北", "year": "2020", "price": "6", "id": "24", "dept": "河南", "settleamount": "202" }, { "amount": "203", "month": "1", "areaname": "华东", "year": "2021", "price": "6", "id": "25", "dept": "辽宁", "settleamount": "203" }, { "amount": "204", "month": "2", "areaname": "华东", "year": "2021", "price": "6", "id": "26", "dept": "辽宁", "settleamount": "204" }, { "amount": "205", "month": "1", "areaname": "华南", "year": "2021", "price": "5", "id": "27", "dept": "湖北", "settleamount": "205" }, { "amount": "206", "month": "2", "areaname": "华南", "year": "2021", "price": "5", "id": "28", "dept": "湖北", "settleamount": "206" }, { "amount": "207", "month": "1", "areaname": "华南", "year": "2021", "price": "5", "id": "29", "dept": "安徽", "settleamount": "207" }, { "amount": "208", "month": "2", "areaname": "华南", "year": "2021", "price": "5", "id": "30", "dept": "安徽", "settleamount": "208" }, { "amount": "203", "month": "1", "areaname": "华东", "year": "2020", "price": "6", "id": "43", "dept": "天津", "settleamount": "203" }, { "amount": "204", "month": "2", "areaname": "华东", "year": "2020", "price": "6", "id": "44", "dept": "天津", "settleamount": "204" }, { "amount": "203", "month": "1", "areaname": "华东", "year": "2021", "price": "6", "id": "45", "dept": "天津", "settleamount": "203" }, { "amount": "204", "month": "2", "areaname": "华东", "year": "2021", "price": "6", "id": "46", "dept": "天津", "settleamount": "204" }] } ~~~
