This field contains ID of the POS menu that controls the look of the leftmost column in the timeline view of the Allocation panel. The leftmost column contains the description of the dining tables.
The Rows field of the menu controls how many dining tables are listed on each page of the timeline view.
Here you also select what text information is displayed as description and/or glyph text by selecting POS tags starting with <#TR-AL-E-, such as the <#TR-AL-E-Capacity%1> tag that displays the capacity of the dining table.
