This builder lets you merge fields so that they are presented as a single field and lets you merge columns so that they are presented as a single column.
You typically have a situation in which your data needs to be in multiple fields. However, when you display the data, you would like these multiple fields to line up on the display as fields that they occupy only one column. For example, a person's address could consist of separate city, state, and ZIP code fields. You can use the Data Field Merge builder to treat separate fields as a single field on a details page or as a single display column.
In the Design panel, you can select multiple fields to be merged, right-click, and click Merge Fields
to merge the fields into the current column. The multiple fields must all be in the same container field. After you fill in the information related to the menu command, the Data Field Merge builder is added to your model and the newly merged columns are displayed.
The builder lets you switch the label and add separators between the fields.
