二、打开PowerDesigner，创建物理模型(Physical Data Model)

三、在PowerDesigner菜单栏中，依次点击“Tools ->Excute Commands->Edit/Run Script..

四、修改如下脚本，指定excel所在路径及文件名：

Option Explicit  
    Dim mdl " the current model  
    Set mdl = ActiveModel  
    If (mdl Is Nothing) Then  
       MsgBox "There is no Active Model"  
    End If  
    Dim HaveExcel  
    Dim RQ  
    Dim x1sApp,xlsWorkBook,xlsSheet 
    RQ = vbYes "MsgBox("Is Excel Installed on your machine ?", vbYesNo + vbInformation, "Confirmation")  
    If RQ = vbYes Then  
       HaveExcel = True  
       " Open & Create Excel Document  
       Set x1sApp = CreateObject("Excel.Application")  
       set xlsWorkBook = x1sApp.Workbooks.Open("J:user.xls")   "指定excel文档路径  
       set xlsSheet = x1sApp.Workbooks(1).Worksheets("Sheet1")   "指定要打开的sheet名称，这里一定要留意
    Else  
       HaveExcel = False  
    End If  
    a x1sApp, mdl,x1sApp,xlsWorkBook,xlsSheet  
    sub a(x1, mdl,x1sApp,xlsWorkBook,xlsSheet)  
    dim rwIndex     
    dim tableName  
    dim colname  
    dim table  
    dim col  
    dim count  
    dim rowCount
     rowCount = xlsSheet.usedRange.Rows.Count
    on error Resume Next  
    For rwIndex = 1 To rowCount   "指定要遍历的Excel行标  从第1行开始  
            With xlsSheet
                If .Cells(rwIndex, 2).Value = "" Then "如果遍历到第二列为空，则退出  
                   Exit For  
                End If
                If .Cells(rwIndex, 3).Value = "" Then "如果遍历到第三列为空，则此行为表名  
                   set table = mdl.Tables.CreateNew     "创建表  
                    table.Name = .Cells(rwIndex , 1).Value "指定表名，第二列的值  
                    table.Code = .Cells(rwIndex , 2).Value   
                    table.Comment = .Cells(rwIndex , 1).Value "指定表注释，第一列的值  
                    count = count + 1  
					"跳过表名下面的表头
					rwIndex = rwIndex + 1
                Else  
                   set col = table.Columns.CreateNew   "创建一列/字段  
                   "MsgBox .Cells(rwIndex, 1).Value, vbOK + vbInformation, "列"              
                   col.Name = .Cells(rwIndex, 1).Value   "指定列名         
                   "MsgBox col.Name, vbOK + vbInformation, "列"  
                   col.Code = .Cells(rwIndex, 2).Value   "指定列名                          
                   col.DataType = .Cells(rwIndex, 3).Value "指定列数据类型             
                     "MsgBox col.DataType, vbOK + vbInformation, "列类型"                 
                   col.Comment = .Cells(rwIndex, 7).Value  "指定列说明  
					"如果主键列值为PK则设置该列为主键
                    If .Cells(rwIndex, 4).Value = "PK" Then                   
                         col.Primary = true                  
                    End If
					"如果默认值列不为空，则设置默认值
					If .Cells(rwIndex, 5).Value <> "" Then                   
                         col.DefaultValue = .Cells(rwIndex, 5).Value            
                    End If
					"如果非空列值为NOTNULL则设置该列为非空
                    If .Cells(rwIndex, 6).Value = "NOTNULL" Then                   
                        col.Mandatory =true                  
                    End If
                End If    
            End With  
    Next  
    MsgBox "生成数据表结构共计 " + CStr(count), vbOK + vbInformation, "表"  
    xlsWorkBook.Close
    x1sApp.Quit
    set x1sApp = nothing
    set xlsWorkBook = nothing
    Exit Sub  
    End Sub

五、点击Run按钮，生成结果如下：
