AXLSX合并样式中的单元格

我正在使用ruby gem axlsx并想知道是否有办法在样式中设置合并列?今天我这样做:

sheet.merge_cells "A1:E1"
sheet.add_row [I18n.t('foo.some_label').upcase], style: [title]
sheet.merge_cells "B2:E2"
...

我想避免手动递增细胞(B2:E2 ... B5:E5),有办法做到这一点吗?

答案 0 :(得分:6)

是的尝试一下(*免责声明我实际上没有测试过这些方法,但我过去使用过类似的功能)

def merge_last_row(sheet,options ={})
  last_row = sheet.rows.last.index + 1
  first_col,last_col = options[:columns]
  if first_col && last_col
    sheet.merge_cells "#{first_col}#{last_row}:#{last_col}#{last_row}"
  else
    sheet.merge_cells sheet.rows.last
  end
  sheet.rows.last.style = style if options[:style]
end

所以要做你想做的事情

merge_last_row sheet, columns:["A","E"]
sheet.add_row [I18n.t('foo.some_label').upcase]
merge_last_row sheet, columns:["B","E"], style:title

如果最后一行包含A-E中的数据,那么列可以留空,它将合并整行。如果没有,你可以添加一个填充列的选项

def fill_columns(sheet,column_count,options={})
  row = options[:row_data] || []
  (column_count - row.count).times do 
    row << nil
  end
  sheet.add_row row
end

调用

my_row = ["Hello","World"]
fill_columns sheet, 5,row_data: my_row
# this will add a row like["Hello","World",nil,nil,nil]
# so that it will merge properly across the columns A-E
merge_last_row sheet

如果您要一致地使用这些函数,那么将这些函数修补到Worksheet可能会更有意义,因此您不必传递sheet对象。

module Axlsx
  class Worksheet
    def merge_last_row(options={})
       last_row = rows.last.index + 1
       first_col,last_col = options[:columns]
       if first_col && last_col
         merge_cells "#{first_col}#{last_row}:#{last_col}#{last_row}"
       else
         merge_cells rows.last
       end
       rows.last.style = style if options[:style]
    end
    def fill_columns(column_count,options={})
      row_data = options[:row_data] || []
      (column_count - row.count).times do 
        row_data << nil
      end
      add_row row_data
    end
  end
end

呼叫

sheet.merge_last_row columns:["A","E"]
sheet.add_row [I18n.t('foo.some_label').upcase]
sheet.merge_last_row columns:["B","E"], style:title
