axlsx_rails gem：列宽问题

Question

I'm using axlsx_rails gem to write in .xlsx file. I have multiple columns in spreadsheet based on form fields. It can vary.

I would like to set the column width for all the columns based on data available.

I have used:

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.

Is is possible to pass an array to column_widths method or any other ways to convert col_widths array values to so that we can pass it to column_widths method?

Thank you.

Answer 1

The method takes a list of column widths, not an array .

You can use the splat operator to convert your array into a list. Simply add a * character:

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
