对虾-在表格单元格中添加图像和文本。
对虾-在表格单元格中添加图像和文本。
提问于 2014-01-14 11:08:50
是否可以使用gem对虾将图像与文本嵌入到表格单元格中？
我用的是gem "prawn", "~> 0.13.2"
我只能嵌入图像或文本。但不是两者都是。请帮帮忙。
Rails版本: 3.2.13和Ruby2.0.0

下面是手册中关于如何将图像和文本插入PDF文档的代码：
text "Scale by setting only the width"
image "#{Prawn::DATADIR}/images/pigs.jpg", :width => 150
move_down 20
text "Scale by setting only the height"
image "#{Prawn::DATADIR}/images/pigs.jpg", :height => 100
move_down 20
text "Stretch to fit the width and height provided"
image "#{Prawn::DATADIR}/images/pigs.jpg", :width => 500, :height => 100下面是手册中关于如何将图像和文本插入PDF-文档的表格单元格的代码：
cell_1 = make_cell(:content => "this row content comes directly ")
cell_2 = make_cell(:content => "from cell objects")
two_dimensional_array = [ ["..."], ["subtable from an array"], ["..."] ]
my_table = make_table([ ["..."], ["subtable from another table"], ["..."] ])
image_path = "#{Prawn::DATADIR}/images/stef.jpg"
table([ ["just a regular row", "", "", "blah blah blah"],
[cell_1, cell_2, "", ""],
["", "", two_dimensional_array, ""],
["just another regular row", "", "", ""],
[{:image => image_path}, "", my_table, ""]])有关自定义表单元格映像的详细信息：查看对虾文档
