The table waits, but the data is wrong. A new column will fix it.

In databases and spreadsheets, adding a new column is a core operation. It can hold fresh metrics, track new states, or store computed values. Done well, it keeps a system agile. Done poorly, it leaves behind technical debt that resists cleanup. A new column is more than a field name.
