参考代码

Dim dttable = DataTables("表A")

Dim app As New MSWord.Application
try
    Dim doc = app.Documents.add
    Dim dt2 As DataTable = dttable
    doc.Tables.Add(Range:=app.Selection.Range,NumRows:=1, NumColumns:= dt2.DataCols.Count)
    With app.Selection.Tables(1)
        .ApplyStyleHeadingRows = True
        .ApplyStyleLastRow = True
        .ApplyStyleFirstColumn = True
        .ApplyStyleLastColumn = True
        .Style = "网格型"
    End With
    For Each dc As DataCol In dt2.DataCols
        app.Selection.TypeText(Text:=dc.Name)
        Dim i As Double
        If Double.TryParse(dc.name,i)
            app.Selection.ParagraphFormat.Alignment = 2
        Else
            app.Selection.ParagraphFormat.Alignment = 1
        End If
        app.Selection.MoveRight(Unit:=12)
    Next
    For i As Integer = 0 To dt2.datarows.count-1
        Dim dr As DataRow = dt2.datarows(i)
       
        For j As Integer = 0 To dt2.datacols.count - 1
            Dim dc As DataCol = dt2.datacols(j)
            app.Selection.TypeText(Text:=dr(dc.Name))
            Dim d As Double
            If Double.TryParse(dr(dc.name),d)
                app.Selection.ParagraphFormat.Alignment = 2
            Else
                app.Selection.ParagraphFormat.Alignment = 1
            End If
            If i = dt2.datarows.count-1 AndAlso j = dt2.datacols.count-1
            Else
                app.Selection.MoveRight(Unit:=12)
            End If
        Next
       
    Next
    app.visible = True
catch ex As exception
    app.Quit
finally

End try

改成自己的表名，执行看结果，然后慢慢看懂代码

Dim dttable = DataTables("表A")

Dim app As New MSWord.Application
try
    Dim doc = app.Documents.add
    Dim dt2 As DataTable = dttable
    doc.Tables.Add(Range:=app.Selection.Range,NumRows:=1, NumColumns:= dt2.DataCols.Count)
    With app.Selection.Tables(1)
        .ApplyStyleHeadingRows = True
        .ApplyStyleLastRow = True
        .ApplyStyleFirstColumn = True
        .ApplyStyleLastColumn = True
        .Style = "网格型"
    End With
    For Each dc As DataCol In dt2.DataCols
        app.Selection.TypeText(Text:=dc.Name)
        Dim i As Double
        If Double.TryParse(dc.name,i)
            app.Selection.ParagraphFormat.Alignment = 2
        Else
            app.Selection.ParagraphFormat.Alignment = 1
        End If
        app.Selection.MoveRight(Unit:=12)
    Next
    For i As Integer = 0 To dt2.datarows.count-1
        Dim dr As DataRow = dt2.datarows(i)
       
        For j As Integer = 0 To dt2.datacols.count - 1
            Dim dc As DataCol = dt2.datacols(j)
            app.Selection.TypeText(Text:=dr(dc.Name))
            Dim d As Double
            If Double.TryParse(dr(dc.name),d)
                app.Selection.ParagraphFormat.Alignment = 2
            Else
                app.Selection.ParagraphFormat.Alignment = 1
            End If
            If i = dt2.datarows.count-1 AndAlso j = dt2.datacols.count-1
            Else
                app.Selection.MoveRight(Unit:=12)
            End If
        Next
       
    Next
    app.visible = True
catch ex As exception
    app.Quit
finally

End try

无语，你能不能看懂代码后处理？

不会做，那请具体表格发上来测试。

Dim t = Tables("表A")
Dim cname = "第一列"

Dim app As New MSWord.Application
try
    Dim doc = app.Documents.add
    app.Selection.font.Size = 20 \'字号
    app.Selection.font.Bold = True   \'加粗
    app.Selection.TypeText(Text:="xxx系统表结构" & vbcrlf)
   
    app.Selection.font.Size = 9 \'字号
    app.Selection.font.Bold = False
   
    For k As Integer = 0 To t.Rows.count-1
        If t.Rows(k).IsNull(cname) = False Then
            app.Selection.TypeText(Text:=t.Rows(K)(cname) & vbcrlf)
            Dim tb = doc.Tables.Add(Range:=app.Selection.Range,NumRows:=1, NumColumns:= t.Cols.Count-1)
            With tb
