它可以用于各种事情。我在我的桌子上有一个用于排序的。例如，如果您想在表格或图表中显示"第3周，2023年"作为标签，您可以使用您的列作为排序列。
它可以用来简化每周时间智能，例如创建一个筛选器，可以轻松跨越年度边界等。
英文:
It can be used for various things. I have one in my table for sorting purposes. e.g. if you wanted to display "Week 3, 2023" in a table or chart as a label, you'd use your column as a sort by column.
It called about be used to simplify weekly time intelligence e.g. create a filter this many weeks in the past which easily crosses year boundaries etc

我认为这也与性能有关。如果你在数据库中添加了该列，那么在创建表格时会降低性能，而在周年度准备好后，在报表填充方面会提高性能。不需要在报表端应用任何串联。而且反之亦然。
现在这是我们的决定，我们需要更好的性能。
英文:
I think it's related to performance as well. If you are adding the column in the database, you are losing performance while creating a table and gaining performance on the report population as the week-year is ready. No need to apply any concatenation on the reporting side. And this is true for the opposite way.
Now it's our decision, where we need better performance.
