## A Simple Workbook

#```ruby
if examples.include? :basic
  wb.add_worksheet(:name => "Basic Worksheet") do |sheet|
    sheet.add_row ["First Column", "Second", "Third"]
    sheet.add_row [1, 2, 3]
  end
end
#```

#Using Custom Styles

#```ruby
# Each cell allows a single, predified style.
# When using add_row, the value in the :style array at the same index as the cell's column will be applied to that cell.
# Alternatively, you can apply a style to an entire row by using an integer value for :style.
if examples.include? :custom_styles
  wb.styles do |s|
    black_cell = s.add_style :bg_color => "00", :fg_color => "FF", :sz => 14, :alignment => { :horizontal=> :center }
    blue_cell =  s.add_style  :bg_color => "0000FF", :fg_color => "FF", :sz => 20, :alignment => { :horizontal=> :center }
    wb.add_worksheet(:name => "Custom Styles") do |sheet|

      # Applies the black_cell style to the first and third cell, and the blue_cell style to the second.
      sheet.add_row ["Text Autowidth", "Second", "Third"], :style => [black_cell, blue_cell, black_cell]

      # Applies the thin border to all three cells
      sheet.add_row [1, 2, 3], :style => Axlsx::STYLE_THIN_BORDER
    end
  end
end
#```

##Styling Cell Overrides

#```ruby
#Some of the style attributes can also be set at the cell level. Cell level styles take precedence over Custom Styles shown in the previous example.
if examples.include? :cell_style_override
  wb.add_worksheet(:name => "Cell Level Style Overrides") do |sheet|

    # this will set the font size for each cell.
    sheet.add_row ['col 1', 'col 2', 'col 3', 'col 4'], :sz => 16

    sheet.add_row [1, 2, 3, "=SUM(A2:C2)"]

    # You can also apply cell style overrides to a range of cells
    sheet["A1:D1"].each { |c| c.color = "FF0000" }
    sheet['A1:D2'].each { |c| c.style = Axlsx::STYLE_THIN_BORDER }
  end
end
##```

##Using Custom Border Styles

#```ruby
#Axlsx defines a thin border style, but you can easily create and use your own.
if examples.include? :custom_borders
  wb.styles do |s|
    red_border =  s.add_style :border => { :style => :thick, :color =>"FFFF0000", :edges => [:left, :right] }
    blue_border =  s.add_style :border => { :style => :thick, :color =>"FF0000FF"}

    wb.add_worksheet(:name => "Custom Borders") do |sheet|
      sheet.add_row ["wrap", "me", "Up in Red"], :style => red_border
      sheet.add_row [1, 2, 3], :style => blue_border
    end
  end
end

#```ruby 
# Hacking border styles
if examples.include? :deep_custom_borders
  wb.styles do |s|
    top_bottom =  s.add_style :border => { :style => :thick, :color =>"FFFF0000", :edges => [:top, :bottom] }  
    border = s.borders[s.cellXfs[top_bottom].borderId]
    # edit existing border parts
    border.prs.each do |part|
      case part.name
      when :top
        part.color = Axlsx::Color.new(:rgb => "FFFF0000")
      when :bottom
        part.color = Axlsx::Color.new(:rgb => "FF00FF00")
      end
    end

    border.prs << Axlsx::BorderPr.new(:name => :left, :color => Axlsx::Color.new(:rgb => '0000FF'), :style => :mediumDashed)
    wb.add_worksheet(:name => 'hacked borders') do |sheet|

##Styling Rows and Columns

#```ruby

    wb.add_worksheet(:name => "Columns and Rows") do |sheet|
      sheet.add_row ['col 1', 'col 2', 'col 3', 'col 4', 'col5']
      sheet.add_row [1, 2, 0.3, 4, 5.0]
      sheet.add_row [1, 2, 0.2, 4, 5.0]
      sheet.add_row [1, 2, 0.1, 4, 5.0]

      #apply the percent style to the column at index 2 skipping the first row.
      sheet.col_style 2, percent, :row_offset => 1

      # apply the head style to the first row.
      sheet.row_style 0, head

      #Hide the 5th column
      sheet.column_info[4].hidden = true

      #Set the second column outline level
      sheet.column_info[1].outlineLevel = 2

      sheet.rows[3].hidden = true
      sheet.rows[1].outlineLevel = 2
    end
  end
end
##```


##Specifying Column Widths

#```ruby

    sheet.add_row [2, 3, 4, "=SUM(A3:C3)"]
    sheet.add_row ["total", "", "", "=SUM(D2:D3)"]
    sheet.merge_cells("A4:C4")
    sheet["A1:D1"].each { |c| c.color = "FF0000"}
    sheet["A1:D4"].each { |c| c.style = Axlsx::STYLE_THIN_BORDER }
  end
end
##```

##Add an Image with a hyperlink

if examples.include? :images
  wb.add_worksheet(:name => "Image with Hyperlink") do |sheet|
    img = File.expand_path('./image1.jpeg', File.dirname(__FILE__))
    # specifying the :hyperlink option will add a hyper link to your image.
