Question

im试图从Excel文件生成表和列的列表到txt文件。我的代码只为所有簇生成直到行尾，因为我不知道如何定义变量来限制循环每个表：

此处的代码和excel数据为image Excel data

Dim field As String
Dim table As String
Dim t As Integer
Dim f As Integer
Dim lastrow As Integer
Dim myFile As String
Dim xStr As String

myFile = "D:\table.txt"

With Sheets("Sheet1")
    Open myFile For Output As #1

    table = """table_name"": """ & .Range("I2") & ""","
    Print #1, table

    lastrow = Range("A" & Rows.Count).End(xlUp).Row

    For f = 2 To lastrow
        field = """column_name"": [" & Chr(10) & """" & .Range("B" & f) & """" & Chr(10) & _
        "],"
        Print #1, field
    Next f

    Close #1


End With

我想像下面的代码（CMIIW逻辑），但是如何在vba上编写代码：

for t = 1 to "count table on sheet (i dnt know how to define this value)"
  table = "tablename"
  Print #1, table

  for f = "first row table t + 1" to lastrow table t
    field= "fieldname"
    Print #1, field
  Next f
Next t

基于对user11246173的回答，我知道如何循环作为表数，但是我仍然无法像上面的代码那样获得每个特定单元格的范围。请帮助解决我的代码。

有人可以帮我吗？

在VBA中，工作表表称为ListObjects。它们是一个属于父工作表的集合，并且（除其他属性外）与大多数其他集合对象一样具有一个计数和一个索引。每个ListObject都有许多ListColumns。

Option Explicit

Sub loopLO()

    Dim i As Long, c As Long

    With Worksheets("sheet1")
        For i = 1 To .ListObjects.Count
            Debug.Print .ListObjects(i).Name
            For c = 1 To .ListObjects(i).ListColumns.Count
                Debug.Print .ListObjects(i).ListColumns(c)
            Next c
        Next i
    End With

End Sub
