Instance Method Details

#align=(location) ⇒ Object

Combined method for both horizontal and vertical alignment. Sets the first valid value (e.g. Format#align = :justify only sets the horizontal alignment. Use one of the aliases prefixed with :v if you need to disambiguate.)

This is essentially a backward-compatibility method and may be removed at some point in the future.

def align= location

147
148
149
 
# File 'lib/spreadsheet/format.rb', line 147

def border=(style)
  [:bottom=, :top=, :right=, :left=].each do |writer| send writer, style end
end

#border_color ⇒ Object

Returns an Array containing the colors of the four borders: bottom, top, right, left

end

#border_color=(color) ⇒ Object

Set all four border colors to color (left, right, top, bottom)

#cross_down ⇒ Object

You can set the following boolean attributes:

#cross_down

Draws a Line from the top-left to the bottom-right corner of a cell.

#cross_up

Draws a Line from the bottom-left to the top-right corner of a cell.

#hidden

The cell is hidden.

#locked

The cell is locked.

#merge_range

The cell is in a merged range.

#shrink

Shrink the contents to fit the cell.

#text_justlast

Force the last line of a cell to be justified. This probably makes sense if horizontal_align = :justify

#left

Apply a border style to the left of the cell.

#right

Apply a border style to the right of the cell.

#top

Apply a border style at the top of the cell.

#bottom

Apply a border style at the bottom of the cell.

#rotation_stacked

Characters in the cell are stacked on top of each other. Excel will ignore other rotation values if this is set.
