ruby-on-rails - axlsx_rails gem : Columns width issue

Question

我正在使用 axlsx_rails gem 写入 .xlsx 文件。我在基于表单字段的电子表格中有多个列。它可以变化。

我想根据可用数据设置所有列的列宽。

我用过:

col_widths= [10,20,30,40,50] 
p = Axlsx::Package.new 
p.use_autowidth = true
wb = p.workbook
wb.add_worksheet(:name => 'try') do |sheet|
sheet.add_row ["hi","hello","how","are","you"]
sheet.column_widths col_widths   ##this column widths method doesn't take an array.

是否可以将数组传递给 column_widths 方法或任何其他方法将 col_widths 数组值转换为，以便我们可以将其传递给 column_widths 方法？

谢谢。

Answer 1

The method采用列宽的列表，而不是数组。

您可以使用 splat operator将您的数组转换为列表。只需添加一个 * 字符:

col_widths= [10,20,30,40,50] 
p = Axlsx::Package.new 
p.use_autowidth = true
wb = p.workbook
wb.add_worksheet(:name => 'try') do |sheet|
sheet.add_row ["hi","hello","how","are","you"]
sheet.column_widths *col_widths ## Here I have used the splat operator
