Table views contain lists of items, and the corresponding fields selected by a user. Items in a table may be "selected" by clicking on the item in its row. When an item is selected, the row will highlight, and the adjacent Property Pane will include the properties of the selected item.
For an item, any corresponding Rich Text fields may be viewed by clicking on the Expand icon or press the space bar. That will reveal the Rich Text fields below the row of the corresponding item. To hide the Rich Text field(s), simply click on the Contract icon . The Expand and Contract icons will toggle depending on whether the Rich Text fields are visible.
