+This script formats ledger entries into tables for different currencies and locales.

+Approach:
+- `create_entry`: Creates a `LedgerEntry` object with parsed date.
+- `format_entries`: Formats entries into a table.
+  - Supports 'en_US' and 'nl_NL' locales.
+  - Generates a header row and sorts entries.
+  - Formats date and truncates descriptions.
+  - Formats change according to currency.
