ruby-on-rails - Prawn - 在表格单元格中添加图像和文本

Question

是否可以嵌入 图片 连同 正文 在使用 gem prawn 的表格单元格中？

我正在使用 gem "prawn", "~> 0.13.2"
我只能嵌入图像或文本。但是，两者都不是。请帮忙。

以下是手册中有关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

以下是手册中有关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, ""]])
