Without giving it a lot of thought, I'd do something to the effect of:

rows = [
[ 'col1', 'col2', 'col3' ],
[ 'cOl1', 'Col2', 'col3' ],
[ 'col1', 'COL2', 'COl3' ],
]

output = ''

output << '<table>'
rows.each do |row|
output << '<tr>'
row.each do |col|
output << "<td>#{col}</td>"
end
output << '</tr>'
end
output << '</table>'

puts output

puts %w(1 2 3 4 5 6 7 8 9).map{|x| "<td>" + x + "</td>" }.
join.gsub(/(<td.*?\/td>){3}/,"<tr>\n \\&\n</tr>\n")
