Power Query – 分割列错误值不能为空
我有一个从2个数字开始，然后是字母的列。 我想分解成数字位和字符位。
当我做：
= Table.SplitColumn(#"Duplicated Column","FamilyCode - Copy",Splitter.SplitTextByPositions({0, 2}, false),{"FamilyCode - Copy.1", "FamilyCode - Copy.2"}) I get an error: > Unexpected error: Value cannot be null.

我再次检查列，每行有一个条目，没有空行，没有less于两个字符的行（所有分钟5至10）
任何人的想法？

谢谢
下面是一个更强大的方法，不关心每个string的开头有多less个数字（可以是none）：
删除您的重复列步骤。
然后添加一个名为FamilyCode Number的自定义列
= Text.SplitAny( Text.Lower ( [FamilyCode] ) , Text.Combine ( {"a".."z"} ) ){0})
然后添加另一个自定义列来获取[FamilyCode]的文本部分
= Text.End ( Text.From ( [FamilyCode] ) , Text.Length( [FamilyCode] ) - Text.Length ( [FamilyCode Number] ) )
