我的尝试：

.xls

我得到的错误：

# -*- coding:utf-8 -*-
require 'writeexcel'

# Create a new Excel workbook
workbook = WriteExcel.new('ruby.xls')

# Add a worksheet
worksheet = workbook.add_worksheet

eec =  [
  ['maggie', 'milly', 'molly', 'may'  ],
  [13,       14,      15,      16     ],
  ['shell',  'star',  'crab',  'stone']
  ]

worksheet.write_col('A1', \@eec)

workbook.close

使用找到here的gem文档。

任何人都可以解释为什么会出现这种语法错误，以及我如何解决它？

1 个答案:

答案 0 :(得分：2)

从write_col：

的调用中删除垃圾符号 
- worksheet.write_col('A1', \@eec)
+ worksheet.write_col('A1', eec)
