根据Microsoft文档here，如果FieldInfo是定界的，则不必按任何顺序排列。

列说明符可以按任何顺序排列。如果没有专栏输入数据中特定列的说明符，该列为解析为“常规”设置。

无论我在第一个参数Workbooks.OpenText Filename:=sPath, DataType:=xlDelimited, Comma:=True, FieldInfo:=Array(Array(18, 5), Array(19, 5)), Local:=True中输入什么内容，excel似乎都将第一个数组视为第一列，将第二个数组视为第二列。因此，要到达第18和19列，我必须做到这一点，这并不好：

Array(Array(x, 5), Array(y, 5))

csv文件样本数据：

Workbooks.OpenText Filename:=sPath, DataType:=xlDelimited, Comma:=True, _
    FieldInfo:=Array(Array(1, 1), _
    Array(2, 1), _
    Array(3, 1), _
    Array(4, 1), _
    Array(5, 1), _
    Array(6, 1), _
    Array(7, 1), _
    Array(8, 1), _
    Array(9, 1), _
    Array(10, 1), _
    Array(11, 1), _
    Array(12, 1), _
    Array(13, 1), _
    Array(14, 1), _
    Array(15, 1), _
    Array(16, 1), _
    Array(17, 1), _
    Array(18, 5), _
    Array(19, 5)), _
    Local:=True

Answer 1

我能够使用.txt文件并使用Tab=True重现此问题：

Workbooks.OpenText Filename:=Path & "Testfile.txt", DataType:=xlDelimited, Tab:=True, FieldInfo:=Array(Array(18, 9), Array(19, 9)), Local:=True

通过使用值9（xlSkipColumn），我尝试省略第18列和第19列，但第1列和第2列被跳过（Test1和Test2）：

documentation明确指出“列说明符可以按任何顺序排列”，但这似乎是不正确的。第一个数组的第一个元素将始终为列1，第二个数组的第一个元素将始终为列2，并且在对所有数组进行迭代之后，其余的列将使用“常规”设置进行解析。

IMO，这对我来说似乎是个错误。如果不是错误，则说明文档非常混乱，需要重新编写。

Answer 2

这确实看起来像是个错误，或者说明文件具有误导性。一种避免丑陋代码的解决方法是在不定界的情况下导入文本文件，并使用TextToColumns对其进行拆分。这样的事情（奇怪的是似乎起作用了）：

Workbooks.OpenText Filename:=sPath, DataType:=xlDelimited, Comma:=False

Columns("A:A").TextToColumns Destination:=Range("A1"), _
    DataType:=xlDelimited, _
    TextQualifier:=xlDoubleQuote, _
    ConsecutiveDelimiter:=False, _
    FieldInfo:=Array(Array(18, 4), Array(19, 4))

Workbooks.OpenText忽略FieldInfo列参数
