By default, a header is inserted into the list every time the value of the grouped column changes. Sometimes you may wish to specify your own rules for grouping a list. For example, you may wish to group the sender column into the following three ranges:
Sender names (A to J)
Sender names (K to R)
Sender names (S to Z)
You can do this by specifying a group range. Having selected 'Sender' in the Field drop down list in the Group dialog box, press the Edit Ranges button. The Ranges dialog box is displayed.
Press the New button. The Range Wizard will appear showing the Name page.
Enter a name for the range, for example, 'Three way alphabetic split', and press Next to display the Ranges page.
The Ranges list will contain a single item called 'All'. You may split this item into the various ranges using the Split button. Press the Split button to display the Data dialog box.
Enter the 'K' character and press OK. The Ranges list will contain the following items:
Up to K
K and above
Press the Split button once more and enter the 'S' character and press OK. The Ranges list will now contain the following items:
Up to K
K to S
S and above
Press Finish on the Ranges page and press OK on the Ranges dialog box. Select the 'Three way alphabetical split' range from the Ranges drop down list in the Group dialog box and press OK. The mail shown in the Incoming Mail folder will be re-grouped as shown below:
The Data dialog box, shown when you press the Split button in the Ranges page, will vary depending upon the data type of the grouping column. If the grouped column is a string type then the Data dialog box will let you split the groupings by string-based ranges. If the grouped column is a date type then the Data dialog box will contain a Date control letting you split the groupings by Date-based ranges as shown below:
A different Data dialog box is displayed for each of the following column data types:
| String | Number | Real |
| Yes/No | Date | Time |
| Date/Time | Duration | Currency |
| Phone | Email Address | Web Address |
| Colour | Link | Selection |
