dataset中有一表datatable，怎样向datatable中加入新列并且给值？？

[lqingniao11]

datatable:

c1 c2 c3 newc

a1 b1 c1 new1
a2 b2 c2 new2
a3 b3 c3 new3

Dim dc As DataColumn
dc = New DataColumn
dc.ColumnName = "newc"
dataTables.Columns.Add(dc)
增加了新列

怎么在相应的行上增加 new1,new2,new3的值呢

不知道大家能不能明白这意思啊

[wangsaokui]

[Visual Basic]
Private Sub AddColumn()
Dim cols As DataColumnCollection
Dim myCol As DataColumn
' Get the DataColumnCollection of a table in a DataSet.
cols = DataSet1.Tables("Orders").Columns
' Add a new column and return it.
myCol = cols.Add("Total", System.Type.GetType("System.Decimal"), _
"Price + Tax")
myCol.ReadOnly = True
myCol.Unique = False
End Sub

[lqingniao11]

myCol = cols.Add("Total", System.Type.GetType("System.Decimal"), _
"Price + Tax")


能否解释一下这行

[lqingniao11]

table1：

c1 c2 c3

a1 b1 c1
a2 b2 c2
a3 b3 c3

table2：只有一行
ca cb cc cd

dt1 dt2 dt3 dt4

能否把table2 加到table1任一行后面？？

c1 c2 c3 ca cb cc cd

a1 b1 c1
a2 b2 c2 dt1 dt2 dt3 dt4
a3 b3 c3
