ruby-on-rails - Axlsx - 格式化单元格内的文本

Question

我似乎找不到任何关于是否可以用多个格式选项填充单个单元格的信息。

例如，我希望单元格 A1 填充文本:“你好世界，这是excel”

这可能吗？如果可以，我应该使用什么语法来做到这一点？

Answer 1

对于内联样式，请使用富文本。 Here is an example from the axlsx page:

  p = Axlsx::Package.new
  p.use_shared_strings = true
  wb = p.workbook
  wrap_text = wb.styles.add_style({:alignment => {:horizontal => :center, :vertical => :center, :wrap_text => true}}  )
  rt = Axlsx::RichText.new
  rt.add_run('I\'m bold, ', :b => true)
  rt.add_run('I\'m italic, ', :i => true)
  rt.add_run('I\'m strike' + "\n", :strike => true)
  rt.add_run('I\'m bold, italic and strike' + "\n", :b => true, :i => true, :strike => true)
  rt.add_run('I\'m style-less :D')
  wb.add_worksheet(:name => "RichText") do | sheet |
    sheet.add_row [rt], :style => wrap_text
  end
  p.serialize 'rich_text.xlsx'

如果您只是想对一个单元格应用多种样式，则需要不同的样式。有两种选择:

首先，手动完成。基本上你声明你的样式类型是 :dxf。默认为 :xf。其他一切都一样。 From the docs on styles.rb:

p = Axlsx::Package.new
wb = p.workbook
ws = wb.add_worksheet

# define your styles
profitable = wb.styles.add_style(:bg_color => "FFFF0000",
                           :fg_color=>"#FF000000",
                           :type => :dxf)

ws.add_row ["Genreated At:", Time.now], :styles=>[nil, date_time]
ws.add_row ["Previous Year Quarterly Profits (JPY)"], :style=>title
ws.add_row ["Quarter", "Profit", "% of Total"], :style=>title
ws.add_row ["Q1", 4000, 40], :style=>[title, currency, percent]
ws.add_row ["Q2", 3000, 30], :style=>[title, currency, percent]
ws.add_row ["Q3", 1000, 10], :style=>[title, currency, percent]
ws.add_row ["Q4", 2000, 20], :style=>[title, currency, percent]

ws.add_conditional_formatting("A1:A7", { :type => :cellIs, :operator => :greaterThan, :formula => "2000", :dxfId => profitable, :priority => 1 })
f = File.open('example_differential_styling', 'w')
p.serialize(f)

其次，使用axlsx_styler gem 。这使得应用多种样式变得非常容易。
