iOS Table
From Xojo Documentation
A Table is used to display lists of data. Tables can display information in sections, can have "accessories" to indicate that more information is available. Each row of a Table can display images and up to 2 lines of text. In addition you can customize the rows of a table to show pretty much whatever you want.
Below is a list of commonly used events, properties and methods. Refer to iOSTable in the Language Reference for the complete list.

Cell Data
When working with a Table, you will need to manage its rows. The class iOSTableCellData contains information about a row in a table. To populate a table manually, you can create instances of iOSTableCellData (using iOSTable.CreateCell), set its properties and then add it to the Table. Or you can add rows using just a subset of values manually.
Use the RowData method to get the iOSTableCellData for a specific row, which you can then use or modify to change what is displayed.
Below are commonly used properties. Refer to iOSTableCellData in the Language Reference for the complete list.
Properties
- The type of (optional) accessory to display for the row. This uses the AccessoryTypes enumeration to choose the type of accessory: None, Disclosure, Detail, Checkmark.
- The Detail Text is smaller text that displays below the main text for the row.
- When an image is specified, it appears in front of the row Text.
- The Tag is an Auto that can be used to store any useful, related information about the cell for retrieval later (such as a primary key to a database or an instance of a class containing additional information).
- The main text that is displayed for the cell row.
