Row Labels allow you to choose the most important columns in a table. Row labels determine which columns are prominently displayed for that table, kind of like a title. One image column and one non-image column can be used as labels. All tables have a non-image label.
You designate the Row Label on the Data > Columns tab by setting the "Row Label" attribute to true for the appropriate column.
You can create a Row Label containing values from two or more columns as follows:
Add a virtual column to the table.
In the app formula field of the virtual column, enter a CONCATENATE expression that combines appropriate column values to form the row label. For example: CONCATENATE([First label column], ", ", [Second label column])
Reset the "Row Label" property for any existing row label column.
Set the "Row Label" property of the virtual column.
Save your changes.
Row Labels are used throughout the app, different views use them differently.
In the Deck view the image label is used for the image on the left, and the non-image label is used as the top text.
In the Table view the non-image label is the first column shown. (unless you have a custom Column Order)
In the Gallery view the image label is used for the image, and the non-image label is used as text below the image
In the Detail view (previously Slideshow view) the image label is shown as a large image on top, and the non-image label is shown directly below the image.
The Ref popup, which is shown when choosing a Ref row from the form, also uses the labels as shown in the Property Audit sample.
