你可以为分组选项设置一个公式或一个相关字段。
切片列可以以同样的方式支持公式和相关字段。
使用DATEPART公式可以帮助对日期类型的字段进行分组，其语法如下。
参数
描述
date_value
(必填)日期值。
format_string
(必填)日期的格式字符串。
[week_num_type]
(可选) 与WEEKNUM的第二个参数相同。
DATEPART公式格式字符串的示例
格式
结果
描述
yyyyQ
20214
数字：1位数（季度编号/名称。）
yyyyQQ
202104
数字：2位数+零点占位
yyyyQQQ
2021Q4
缩略
yyyy QQQQ
2021 4th quarter
全描述
YYYY w
2021 8
数字：最小数字(年度周(数字)。当与年份一起使用时，在年份字段中使用'Y'）。
YYYY ww
2021 08
数字：2位数，如果需要的话，可以用零占位。
MM-yyyy
09-2021
在单元格格式化中提供部分日期格式化
使用CALCULATE和REMOVEFILTERS公式可以帮助扩大组的范围，其语法如下。
参数
描述
formula_string
(必填) 该公式将通过expand_context的上下文进行计算。
expand_context
(必填) expand_context来自REMOVEFILTERS。
参数
描述
[group_field_string]
(可选）组字段表示被扩展到的范围。
CALCULATE只能在summaryFields选项的公式选项中使用，而REMOVEFILTERS只能用于REMOVEFILTERS和CALCULATE的组合。
