The Pack function takes data from multiple input columns and packs it into a single column. The packed column has a virtual column for each input column. By default, virtual columns are separated by commas and each virtual column value is labeled with its column name.
Pack is complementary to the function Unpack, but you can use it on any input columns that meet the input requirements.
Before packing columns, note their data types—you need them if you want to unpack the packed column.
