如何在整个 table 中搜索 Powerquery 中的短语

Question

如果整个 table 包含任何列或任何行中的搜索值，如何检查 powerquery。假设我们有一个 table:

+------------+-----------+---------+
|  column1   |  column2  | column3 |
+------------+-----------+---------+
| apple      | banana    | cherry  |
| damson     | entawak   | fig     |
| watermelon | wolfberry | plum    |
+------------+-----------+---------+

我要查找哪一列哪一行有wolfberry？它是c=2和r=3。我想使用坐标进行进一步的数据处理。

为了方便起见，这里是示例 table 的代码：

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSiwoyElV0lFKSswDQiAjOSO1qKhSKVYnWiklMbc4Pw8olppXkliemH1oAZCdlpkOlixPLEktyk3NASsoz89JSwLr01EqyCnNVYqNBQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t, Column3 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Column2", type text}, {"Column3", type text}})
in
    #"Changed Type"

您可以使用以下技巧：

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSiwoyElV0lFKSswDQiAjOSO1qKhSKVYnWiklMbc4Pw8olppXkliemH1oAZCdlpkOlixPLEktyk3NASsoz89JSwLr01EqyCnNVYqNBQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t, Column3 = _t]),
    func = (word) =>
            [r = Table.AddIndexColumn(Source, "r", 1, 1),
             c = Table.AddIndexColumn(Table.Transpose(Source), "c", 1, 1),
             coordinates = [r = Table.FindText(r, word)[r]{0}, c = Table.FindText(c, word)[c]{0}]
            ][coordinates],
    search = func("wolfberry")
in
    search
