Table.PositionOf

Table.PositionOf(table as table, row as record, optional occurrence as nullable number, optional equationCriteria as any) as any

返回 row 在指定的 table 中第一次出现的行位置。如果找不到该值,则返回 -1。

  • table: 输入表。
  • row: 表中要查找其位置的行。
  • occurrence: [可选] 指定要返回的行的出现次数。
  • equationCriteria: [可选] 控制表行之间的比较。
示例:

查找 [a = 2, b = 4] 在表 ({[a = 2, b = 4], [a = 6, b = 8], [a = 2, b = 4], [a = 1, b = 4]}) 中第一次出现的位置。

使用情况:

Table.PositionOf(Table.FromRecords({[a = 2, b = 4], [a = 1, b = 4], [a = 2, b = 4], [a = 1, b = 4]}), [a = 2, b = 4])

输出:

0

示例:

查找 [a = 2, b = 4] 在表 ({[a = 2, b = 4], [a = 6, b = 8], [a = 2, b = 4], [a = 1, b = 4]}) 中第二次出现的位置。

使用情况:

Table.PositionOf(Table.FromRecords({[a = 2, b = 4], [a = 1, b = 4], [a = 2, b = 4], [a = 1, b = 4]}), [a = 2, b = 4], 1)

输出:

2

示例:

查找 [a = 2, b = 4] 在表 ({[a = 2, b = 4], [a = 6, b = 8], [a = 2, b = 4], [a = 1, b = 4]}) 中所有出现的位置。

使用情况:

Table.PositionOf(Table.FromRecords({[a = 2, b = 4], [a = 1, b = 4], [a = 2, b = 4], [a = 1, b = 4]}), [a = 2, b = 4], Occurrence.All)

输出:

{0, 2}
