There is the option to view the rows of tabular data differently. The different view formats can be found right next to the 'Find in this Dataset' field, to the upper right-hand side of the dataset.
1. View as a Table
This is what you will always see by default - rows of equal height but variable width. If they contain content which cannot be displayed the area of the cell, you can see it only upon hovering on the cell. You can scroll through the dataset to view all the rows.
An example of a dataset in a tabular view:
2. View as a Rich List
This rich list view retains the rows but increases the height so that all of the content appears without the need for hovering. You would still need to scroll to view all the data if there was a lot of it, and you can still scroll all the way down to see the remaining rows in the table.
An example of a dataset in a rich list:
3. View as a Single Row
The right-most option is 'view as a single row' - this will allow a single rows content to be displayed in a full view, where each column will be seen as a section with the respective content falling underneath. However here only a single rows content is displayed in a static view - you would then need to page through each row to see the other row content.
Editing the view layout
For (2) and (3) you also have the option of editing the layout in which the content is displayed which is the Edit Layout button in the bottom left of these views. These can be used to help in usability and accessibility to datasets which have a lot of data in cells which cannot be seen without hovering on the cell.
You can also choose to see more than one of these views to appear at the same time - you need to select at minimum one at all times, but can select up to all three to appear at once.
