table position

[macsig]

Hello, is it possible to define where a table should be placed?
Something like :at => [x,y] for text

Moreover, I found the option to show the total number of pages, is it
possible to show the current page number?


Thank you and have a nice day!

You can use a bounding box for that.

bounding_box([100,500]) do
table data, ...
end

You can also set the x position of a table with :position => xpos

page_count will always be the current page number, as your pages are
finalized each time a new one begins.
We don't currently have a way of getting the 'true' total page count.

Hello Gregory and thanks for you reply.

I have some issue with the bounding box:

My code looks like:

Prawn::Document.generate("doc.pdf", :page_layout => :landscape) do

img = "#{RAILS_ROOT}/public/images/img.png"
image img, :at => [0,500], :scale => 0.50

bounding_box([10,500]) do
data = ["a","b"]


table data,
:position => :center,
:font_size => 10,
:headers => ["1","2"],
:row_colors => ["ffffff", "c2ced7"],
:vertical_padding => 4,
:horizontal_padding => 3
end
end

and I get a "comparison of Float with nil failed" error

/Library/Ruby/Gems/1.8/gems/prawn-0.1.2/lib/prawn/document/table.rb:
159:in `calculate_column_widths'

Am I missing something?

Thanks again and have a nice day!

Yes. data needs to be a two dimensional array, representing an array
of rows of cells.

data = [["a","b"]]

I'll work on throwing a better error message, please drop a ticket in
Lighthouse to remind me.

Whoops:

You also need to specify a width for your bounding box.

[macsig]

My bad, simplifying the code to post I have deleted [],


Now my code looks like:

Prawn::Document.generate("doc.pdf", :page_layout => :landscape) do
img = "#{RAILS_ROOT}/public/images/img.png"
image img, :at => [0,500], :scale => 0.50
bounding_box([10,500]) do
data = [["a","b"]]
table data,
:position => :center,
:font_size => 10,
:headers => ["1","2"],
:row_colors => ["ffffff", "c2ced7"],
:vertical_padding => 4,
:horizontal_padding => 3
end
end

and I get a "You have a nil object when you didn't expect it! You
might have expected an instance of Array. The error occurred while
evaluating nil." error
and the line with error is table data. Removing the box everything
works fine.

Am I still missing something?

Thanks buddy.

Yes. All bounding_box calls require a :width parameter.

I'll add a better error for this, too.

[macsig]

got it !!!

Thanks

a ticket about the first error message has been open
