You should subscribe to the ColumnChanged event, that way you can see the previous and current values.

您应该订阅ColumnChanged事件，这样就可以看到以前和当前的值。

Example:

例子:

//code to wire up the handler
custTable.ColumnChanged += new DataColumnChangeEventHandler(Column_Changed);

//code for the event
private static void Column_Changed(object sender, DataColumnChangeEventArgs e )
{
    Console.WriteLine("Column_Changed Event: name={0}; Column={1}; original name={2}", 
        e.Row["name"], e.Column.ColumnName, e.Row["name", DataRowVersion.Original]);
}
