Exercise 1: Loading and Displaying Data (Solution)

This is a solution to Exercise 1. You need the sample files booklist.csv and country-codes.csv. Alternatively, if you want to use data from the samples SQL database, remember to use datatooltk to import the data to a .dbtex file and load it using \DTLloaddbtex as described in Loading Data From a .dbtex File.

Note that two LaTeX runs are required for the longtable to correctly align the table columns. This is a feature of the longtable package. (Two LaTeX runs are also required to get the cross-references up-to-date.)
