From: chen li Date: 2006-12-12T04:33:34+09:00 Subject: Re: format problem Hi Paul, Thank you so much for your time and input. I just need to print a 2D array to screen in the following format: [ [1,2,3,4,5,6,7,8,9,10,11,12], [13,14,15,16,17,18,19,20,21,22,23,24], ... [85,86,87,88,89,90,91,92,93,94,95,96]] After I create a 2D array of 8 row x12 column 2D from a 1D array I want to print this format directly to the screen without writing further code lines. If the column number is less than 10 I can print the data(using pp) in the format above but if column number is 12 I can't. To solve this the only thing I can do is to write another loop(see below) to go through to the same 2D again. _2D_array.each{|i| puts i} Li ____________________________________________________________________________________ Any questions?
