通过Axlsx添加到电子表格时正确设置Excel列宽

Question

我正在尝试格式化我的报告并确保列具有正确的宽度，而我似乎无法通过auto_width实现这一点。

使用此代码，这是我得到的报告。请注意auto_width的长度空间，因为如果我双击Excel中的每个列边框，它会正确调整大小，请参阅此图片。

也许这就是我正在做的事情？

这是我正在使用的代码：

workbook = xlsx_package.workbook
worksheet_name = 'My Worksheet'
xlsx_package.use_autowidth = true

# Styles init
header_style = workbook.styles.add_style               :bg_color => "D8D8D8",
                                                   :b => true,
                                                   :border => { :style => :thin, :color => "00" },
                                                   :alignment => { :horizontal => :center,
                                                                   :vertical => :center ,
                                                                   :wrap_text => false}
totals_style = workbook.styles.add_style               :bg_color => "D8D8D8",
                                                   :b => true,
                                                   :border => { :style => :thin, :color => "00" },
                                                   :alignment => { :horizontal => :center,
                                                                   :vertical => :center ,
                                                                   :wrap_text => false}
odd_row_style = workbook.styles.add_style              :bg_color => "A9E2F3",
                                                   :border => { :style => :thin, :color => "00" },
                                                   :alignment => { :horizontal => :center,
                                                                   :vertical => :center ,
                                                                   :wrap_text => false}
even_row_style = workbook.styles.add_style             :bg_color => "CEECF5",
                                                   :border => { :style => :thin, :color => "00" },
                                                   :alignment => { :horizontal => :center,
                                                                   :vertical => :center ,
                                                                   :wrap_text => false}
merged_title_cell_style = workbook.styles.add_style    :bg_color => "D8D8D8",
                                                   :b => true,

                                                   :alignment => { :horizontal => :center,
                                                                   :vertical => :center ,
                                                                   :wrap_text => true}

workbook.add_worksheet(:name => worksheet_name) do |sheet|
  # Add empty row for aesthetics
  sheet.add_row([''], :height => 8)

  # We add the meta header row
  meta_header_row = ['', "Meta header 1", '', '', '', '', '', '', '', '', '', "Meta header 2", '', '', '', '']
  sheet.add_row(meta_header_row, :style => merged_title_cell_style, :height => 30)
  sheet.merge_cells('B2:K2')
  sheet.merge_cells('L2:P2')

  @data = Array.new
  @data << ['John', 1, 2, 3, 4, 5, 6, 7, 8, 9 ,10, 11, 12, 13, 14, 15]

  # Styling
  sheet.col_style(0, header_style)

  # We keep the first 2 cells white
  sheet.rows[0..1].each{|row| row.cells[0].style = 0}

  sheet.auto_filter = "A3:A#{sheet.rows.count}"
end

谢谢你的帮助！

我也遇到过这个问题。我假设你正在寻找那种模仿尽可能接近收缩包裹的解决方案“我只需双击每个列标题”的样子。不幸的是，我发现这很难做到。

可能有用的东西是（未记录的？）宽度类型：

sheet.add_row(meta_header_row, 
  :style => merged_title_cell_style, 
  :height => 30,
  :widths => [:ignore] * meta_header_row.count
)

这告诉Axlsx您仍然希望使用自动宽度来计算列宽，但是在执行此操作时忽略此行中任何单元格的内容。
