Overview

CELL FORMATTING

This section describes the methods and properties that are available for formatting cells in Excel. The properties of a cell that can be formatted include: fonts, colours, patterns, borders, alignment and number formatting.

Creating and using a Format object

Cell formatting is defined through a Format object. Format objects are created by calling the workbook add_format() method as follows:

format1 = workbook.add_format             # Set properties later
format2 = workbook.add_format(props_hash) # Set at creation

The format object holds all the formatting properties that can be applied to a cell, a row or a column. The process of setting these properties is discussed in the next section.

Once a Format object has been constructed and its properties have been set it can be passed as an argument to the worksheet write methods as follows:

worksheet.write( 0, 0, 'One', format )
worksheet.write_string( 1, 0, 'Two', format )
worksheet.write_number( 2, 0, 3, format )
worksheet.write_blank( 3, 0, format )

Formats can also be passed to the worksheet set_row() and set_column() methods to define the default property for a row or column.

worksheet.set_row( 0, 15, format )
worksheet.set_column( 0, 0, 15, format )

Format methods and Format properties

The following table shows the Excel format categories, the formatting properties that can be applied and the equivalent object method:

           Rotation          rotation        set_rotation()
           Text wrap         text_wrap       set_text_wrap()
           Justify last      text_justlast   set_text_justlast()
           Center across     center_across   set_center_across()
           Indentation       indent          set_indent()
           Shrink to fit     shrink          set_shrink()

Pattern    Cell pattern      pattern         set_pattern()
           Background color  bg_color        set_bg_color()
           Foreground color  fg_color        set_fg_color()

Border     Cell border       border          set_border()
           Bottom border     bottom          set_bottom()
           Top border        top             set_top()
           Left border       left            set_left()
           Right border      right           set_right()
           Border color      border_color    set_border_color()
           Bottom color      bottom_color    set_bottom_color()
           Top color         top_color       set_top_color()
           Left color        left_color      set_left_color()
           Right color       right_color     set_right_color()

There are two ways of setting Format properties: by using the object method interface or by setting the property directly. For example, a typical use of the method interface would be as follows:

format = workbook.add_format
format.set_bold
format.set_color( 'red' )

By comparison the properties can be set directly by passing a hash of properties to the Format constructor:

format = workbook.add_format( :bold => 1, :color => 'red' )

or after the Format has been constructed by means of the set_format_properties() method as follows:

format = workbook.add_format
format.set_format_properties( :bold => 1, :color => 'red' )

You can also store the properties in one or more named hashes and pass them to the required method:

font = {
    :font  => 'Arial',
    :size  => 12,
    :color => 'blue',
    :bold  => 1
}

shading = {
    :bg_color => 'green',
    :pattern  => 1
}

format1 = workbook.add_format( font )           # Font only
format2 = workbook.add_format( font, shading )  # Font and shading

The provision of two ways of setting properties might lead you to wonder which is the best way. The method mechanism may be better is you prefer setting properties via method calls (which the author did when the code was first written) otherwise passing properties to the constructor has proved to be a little more flexible and self documenting in practice. An additional advantage of working with property hashes is that it allows you to share formatting between workbook objects as shown in the example above.

Working with formats

The default format is Arial 10 with all other properties off.

Each unique format in WriteXLSX must have a corresponding Format object. It isn't possible to use a Format with a write() method and then redefine the Format for use at a later stage. This is because a Format is applied to a cell not in its current state but in its final state. Consider the following example:

format = workbook.add_format
format.set_bold
format.set_color( 'red' )
worksheet.write( 'A1', 'Cell A1', format )
format.set_color( 'green' )
worksheet.write( 'B1', 'Cell B1', format )

Cell A1 is assigned the Format format which is initially set to the colour red. However, the colour is subsequently set to green. When Excel displays Cell A1 it will display the final state of the Format which in this case will be the colour green.

In general a method call without an argument will turn a property on, for example:

format1 = workbook.add_format
format1.set_bold         # Turns bold on
format1.set_bold( 1 )    # Also turns bold on
format1.set_bold( 0 )    # Turns bold off

Class Method Details

.color(color_code) ⇒ Object

Used in conjunction with the set_xxx_color methods to convert a color string into a number. Color range is 0..63 but we will restrict it to 8..63 to comply with Gnumeric. Colors 0..7 are repeated in 8..15.

Convert hashes of properties to method calls.

The properties of an existing Format object can be also be set by means of set_format_properties():

format = workbook.add_format
format.set_format_properties(:bold => 1, :color => 'red');

However, this method is here mainly for legacy reasons. It is preferable to set the properties in the format constructor:

format = workbook.add_format(:bold => 1, :color => 'red');
