Re: build 3x3 table from one array


#1

I think they are really cool.

I am stuck trying to figure out how to take an array of data and
dynamically build a 3x3 html table from it without standard for loops.

If you don’t mind a 3rd party solution:

require ‘html/table’
include HTML

array = [1,2,3,4,5,6,7,8,9]

table = Table.new
table.push(Table::Row.new(array[0…2]))
table.push(Table::Row.new(array[3…5]))
table.push(Table::Row.new(array[6…9]))

puts table.html

1 2 3
4 5 6
7 8 9
