Defining column ordering
You can define the order of the columns in the table, which will define the order in which they are generated through ACS.
To change the order of columns:
1. Select the table for which you want to reorder the columns.
2. In the Property pages, click the Members tab.
3. Use the directional arrows to position the columns in the required order.
