2. Expected effect
In the original data table, the encoded data is saved, while in the data presentation, the actual values need to be displayed, while the encoding and values are often saved in another table.
For example, in the ordersdetail table of the built-in FRDemo database, there is only ProductID, and the corresponding ProductName is in the products table. You want to display the product ID in the order details report as the corresponding product name, as shown in the following figure:
3. Implementation ideas
1) Method 1: set the actual value and display value by using the display setting in cell attributes

The actual results are not in accordance with the requirements. In this case, you can achieve the following result.
2. Report design

Design the table as following：
Set the formula in cell C2: = split (B2, ","), and add the display setting which reference to Method 1.
2) Set C2 cell expansion direction: none, parent cell: default.
3) Set D2 cell expansion direction: vertical, left parent cell: B2.
