# Spreadsheet::Row

The Row class. Encapsulates Cell data and formatting. Since Row is a subclass of Array, you may use all the standard Array methods to manipulate a Row. By convention, Row#at will give you raw values, while Row#[] may be overridden to return enriched data if necessary (see also the Date- and DateTime-handling in Excel::Row#[]

Useful Attributes are:

idx | The 0-based index of this Row in its Worksheet.
formats | A parallel array containing Formatting information for all cells stored in a Row.
default_format | The default Format used when writing a Cell if no explicit Format is stored in formats for the cell.
height | The height of this Row in points (defaults to 12).

### Attributes

formats[R]
height[RW]
idx[RW]
worksheet[RW]

### Public Instance Methods

default_format() click to toggle source

The default Format of this Row, if you have set one. Returns the Worksheet's default or the Workbook's default Format otherwise.

    # File lib/spreadsheet/row.rb, line 70
    def default_format
      @default_format || @worksheet.default_format || @workbook.default_format
    end

default_format=(format) click to toggle source

Set the default Format used when writing a Cell if no explicit Format is stored for the cell.

    # File lib/spreadsheet/row.rb, line 76
    def default_format= format
      @worksheet.add_format format if @worksheet
      @default_format = format
    end

first_unused() click to toggle source

first_unused (really last used + 1) - the 0-based index of the first of all remaining contiguous blank Cells.

Alias for: formatted_size
first_used() click to toggle source

first_used the 0-based index of the first non-blank Cell.

    # File lib/spreadsheet/row.rb, line 83
    def first_used
      [ index_of_first(self), index_of_first(@formats) ].compact.min
    end

format(idx) click to toggle source

The Format for the Cell at idx (0-based), or the first valid Format in Row#default_format, Column#default_format and Worksheet#default_format.

    # File lib/spreadsheet/row.rb, line 89
    def format idx
      @formats[idx] || @default_format          || @worksheet.column(idx).default_format if @worksheet
    end

formatted() click to toggle source

Returns a copy of self with nil-values appended for empty cells that have an associated Format. This is primarily a helper-function for the writer classes.

    # File lib/spreadsheet/row.rb, line 97
    def formatted
      copy = dup
      Helpers.rcompact(@formats)
      if copy.length < @formats.size
        copy.concat Array.new(@formats.size - copy.length)
      end
      copy
    end

formatted_size() click to toggle source

Same as Row#size, but takes into account formatted empty cells

    # File lib/spreadsheet/row.rb, line 107
    def formatted_size
      Helpers.rcompact(@formats)
      sz = size
      fs = @formats.size
      fs > sz ? fs : sz
    end

Also aliased as: first_unused
inspect() click to toggle source

    # File lib/spreadsheet/row.rb, line 117
    def inspect
      variables = instance_variables.collect do |name|
        "%s=%s" % [name, instance_variable_get(name)]
      end.join(' ')
      sprintf "#<%s:0x%014x %s %s>", self.class, object_id, variables, super
    end

set_format(idx, fmt) click to toggle source

Set the Format for the Cell at idx (0-based).

    # File lib/spreadsheet/row.rb, line 125
    def set_format idx, fmt
      @formats[idx] = fmt
      @worksheet.add_format fmt
      @worksheet.row_updated @idx, self if @worksheet
      fmt
    end

update_format(idx, opts = {}) click to toggle source

    # File lib/spreadsheet/row.rb, line 132
    def update_format(idx, opts = {})
      if @formats[idx]
        @formats[idx].update_format(opts)
      else
        fmt = default_format.clone
        fmt.font = fmt.font.clone
        @formats[idx] = fmt.update_format(opts)
      end
      @worksheet.add_format @formats[idx]
      @worksheet.row_updated @idx, self if @worksheet
    end
