生成支持中文的excel表格

    生成支持中文的excel表格
   
     首先 安装gem
 

 gem install  spreadsheet  # -excel-0.3.5.1

  

class ProductController < ApplicationController
  require 'win32ole'
  require "spreadsheet/excel"
  require "iconv"
  
 def get_excel
    catalogs =  Product.find(:all)
    report_arr = [%w{product_number new_product product_name scale_size}]
    #    report_arr =["姓名" ,"编号","邮箱"]
    report_arr[0] = ["产品编号" ,"新产品编号","产品名称","规格尺寸"]
    catalogs.each do |c|
      report_arr << 

[c.product_number,c.new_product,c.product_name,c.scale_size,]
    end
    now = Time.now.to_s(:db)
    ic = Iconv.new("gbk","utf-8")
    workbook = Excel.new("#{RAILS_ROOT}/public/reports/catalogs.xls")
    worksheet = workbook.add_worksheet("Report of catalogs")
    worksheet.write(0, 0, "#{now}")
    #    worksheet.write(1, 0, ic.iconv(conditions.join(",")))
    report_arr.each_with_index do |row, row_idx|
      row.each_with_index do |cell, col_idx|
        worksheet.write(row_idx+2, col_idx, ic.iconv(cell))
      end
    end
    workbook.close
    @msg = "#{now}<br/>导出完毕。"
    render :layout => true
    
  end
end 

这些代码不用任何修改 你可以直接使用,呵呵 当然你必须有数据库.
下面是我测试的栏数据,大家原谅,这个方法绝对是支持中文的.
