Creating a table
A local weather station in New York needs to track daily temperature readings for a weekly report during an unusual heat wave. The station manager has asked you to create a simple data structure that can be used to generate statistics and visualizations for their weekly climate briefing. The table should help meteorologists identify trends and anomalies in temperature and precipitation patterns.
The Table, DoubleColumn, and StringColumn classes from Tablesaw have been imported for you.
