ruby-on-rails - ruby Prawn gem ，餐 table 位置

Question

使用prawn gem我在pdf文件中显示表格..现在我想设置表格的位置，请指导我如何处理这个..

我使用以下代码生成pdf报告，

pdftable = Prawn::Document.new

pdftable.table([["Name","Login","Email"]],
:column_widths => {0 => 80, 1 => 80, 2 => 80, 3 => 80}, :row_colors => ["d5d5d5"])

 @users.each do|u|
 pdftable.table([["#{u.name}","#{u.login}","#{u.email}"]],
 :column_widths => {0 => 80, 1 => 80, 2 => 80, 3 => 80 }, :row_colors => ["ffffff"])

谢谢

Answer 1

您可以将函数 indent() 与函数 move_down 和 move_up 结合使用，
因此，例如在位置(50,20)(相对于您的光标位置)设置表将如下所示:

move_down 20
indent(50) do #this is x coordinate
    pdftable.table([["Name","Login","Email"]],
    :column_widths => {0 => 80, 1 => 80, 2 => 80, 3 => 80}, :row_colors => ["d5d5d5"])

    @users.each do|u|
    pdftable.table([["#{u.name}","#{u.login}","#{u.email}"]],
    :column_widths => {0 => 80, 1 => 80, 2 => 80, 3 => 80 }, :row_colors => ["ffffff"])
end
