# Simple example of merging cells using the Excel::Writer::XLSX module.
#
# This example merges three cells using the "Centre Across Selection"
# alignment which was the Excel 5 method of achieving a merge. For a more
# modern approach use the merge_range() worksheet method instead.
# See the merge3.pl - merge6.pl programs.
