I m 采用Prawn/Prawnto在铁路中创建一种简单的PDF。 我不敢肯定,如果我的问题与Prawnto有关,或者如果它只是一纸空文。 我认为,以下法典。
This will successfully output a table:
pdf.table([%w[foo boo], %w[bar baz]])
但我要求我检查某些数据单位,如果它们符合某些标准,那么我就必须改写案文。 现在,我知道下面的幻灯塔描述了这些要求,但这是一个例子,我发现,在最初的器块中没有任何评价。
工作
pdf.table([%w[foo boo], %w[bar baz]]) do |t|
t.column(0).width = 200
end
上面的刀切将像以前那样产生我的表格,但第一栏为200宽。 我在<代码>do之后似乎没有评价过。 我已经开完了结,而且我仍然只是提出我的表格,没有错误或警告。 我举出了一些例子,即若不开Prawnto plugin,即可使用直线的Prawn,但不知道这是否是对Prawnto的限制,或者如果我做错的话。
任何想法,我会错做什么?
Seems this syntax isn t supported unless you manually build from git or until the next release: http://groups.google.com/group/prawn-ruby/browse_thread/thread/d52b51b4eac779bb
