ruby - 如何将 Roo excel 表中的数组放入二维数组中

Question

我正在使用 ruby​​ 中的 roo-gem 来获取 excel 表单元格值。

我有一个文件'ruby.rb'：

require 'spreadsheet'
require 'roo'

xls = Roo::Spreadsheet.open('test_work.xls')
xls.each do |row|
  p row
end

当我运行 ruby​​ 'ruby.rb' 时，我在终端中的输出是：

["id", "header2", "header3", "header4"]
["val1", "val2", "val3", "val4"]
["val1", "val2", "val3", "val4"]

当我添加：

require 'spreadsheet'
require 'roo'

xls = Roo::Spreadsheet.open('test_work.xls')
xls.each do |row|
  two_dimensional = []
  two_dimensional << row
  p two_dimensional
end

我得到：

[["id", "header2", "header3", "header4"]]
[["val1", "val2", "val3", "val4"]]
[["val1", "val2", "val3", "val4"]]

我想要的是：

[["id", "header2", "header3", "header4"],
["val1", "val2", "val3", "val4"],
["val1", "val2", "val3", "val4"]]

我将如何去做这件事。

谢谢！

Answer 1

只需在each块外声明数组。您将其重置为[]每次运行该块时。在这种情况下，您只会追加到一个数组。

two_dimensional = []
xls = Roo::Spreadsheet.open('test_work.xls')
xls.each do |row|
  two_dimensional << row
  p two_dimensional
end

你也可以试试

require 'rubygems'
require 'roo'

class InputExcelReader
$INPUTPATH = 'C:\test_input_excel.xlsx'
excel_data_array = Array.new()

workbook = Roo::Spreadsheet.open($INPUTPATH)
worksheets = workbook.sheets
puts worksheets
puts "Found #{worksheets.count} worksheets"

worksheets.each do |worksheet|
    puts "Reading: #{worksheet}"
    num_rows = 0
    workbook.sheet(worksheet).each_row_streaming do |row|
        if(num_rows>0)
            puts "Reading the row no: #{num_rows}"
            row_cells = row.map { |cell| 
                puts "Reading cells"
                cell.value              
            }
            excel_data_array.push(row_cells)            
        end
        num_rows += 1
    end
    puts excel_data_array.to_s
end
end
