當通過Axlsx添加到電子表格時，正確設置Excel列寬

Question

我試圖格式化報告並確保列的寬度正確，我似乎無法使其與auto_width一起發生。

有了這段代碼，這是我得到的那種報告。請注意，如果我雙擊Excel中的每個列邊框，它就會正確調整大小，請參閱。

也許這是我正在做的事情？

這是我使用的代碼：

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, 
                :sz => 16, 
                :border => { :style => :thin, :color => "00" }, 
                :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] 
    @data << ['Jack', 1, 2, 3, 4, 5, 6, 7, 8, 9 ,10, 11, 12, 13, 14, 15] 
    @data << ['Bob', 1, 2, 3, 4, 5, 6, 7, 8, 9 ,10, 11, 12, 13, 14, 15] 
    @data << ['Franck', 1, 2, 3, 4, 5, 6, 7, 8, 9 ,10, 11, 12, 13, 14, 15] 
    @data << ['A total', 4, 8, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64] 
    @data << ['Another total', 4, 8, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64] 

    @data.each_with_index do |data_row, index| 
    if(index == 0) 
     sheet.add_row(data_row, :style => header_style) 
    elsif(index >= @data.count - 2) 
     sheet.add_row(data_row, :style => totals_style) 
    elsif(index.even?) 
     sheet.add_row(data_row, :style => even_row_style) 
    else 
     sheet.add_row(data_row, :style => odd_row_style) 
    end 
    end 

    # 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 

感謝您的幫助！

我也遇到過這個問題。我假設你正在尋找那種儘可能接近收縮包裝的解決方案「我只需雙擊每個列標題」的外觀。不幸的是，我發現這很難做到。

的東西，可以幫助你是一個（無證？）寬度類型：

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

這告訴Axlsx，你仍然要使用autowidth來計算列寬，但忽略任何單元格的內容在這一行中。
