The script `generate.rb` is provided to actually generate the example documents by executing the sample code contained in the markdown files.

+## Description
+
+You can split the sheet into panes. `pane.state` could have three options: `split`, `frozen` or `frozen_split`
+
+## Code
+
+```ruby
+require 'axlsx'
+
+p = Axlsx::Package.new
+wb = p.workbook
+
+wb.add_worksheet(name: 'Panes') do |sheet|
+  # Generate a big dataset
+  sheet.add_row [''] + (0..99).map { |i| "column header #{i}" }
+  100.times { |index| sheet.add_row ['row header'] + (0..index).to_a }
+
+  sheet.sheet_view.pane do |pane|
+    pane.top_left_cell = 'B2'
+    pane.state = :frozen_split
+    pane.y_split = 1
+    pane.x_split = 1
+    pane.active_pane = :bottom_right
+  end
+end
+
+p.serialize 'panes_example.xlsx'
+```
