Generating PDF with tables programmatically

#Beginner #Caché #ZEN

I have this local, containing a list of books of arbitrary length:

set books=2
set books(1, "author") = "Alice"
set books(1, "title") = "Hello"
set books(1, "pages") = "123"
set books(2, "author") = "Bob"
set books(2, "title") = "World"
set books(2, "pages") = "456"

And I want to generate this PDF (there could be more than two tables), each book is a separate table:

The header is always the same (Author, Title, Page) but the number of tables would be different.

ZEN reports sounds relevant, but I'm not sure how to pass data from local there and how to draw a separate table for each result.

Or there is some other solution?

So far I got:

Class Test.Zen Extends %ZEN.Report.reportPage
{

Parameter DEFAULTMODE = "pdf";

/// ReportDefinition is a placeholder.
XData ReportDefinition [ XMLNamespace = "http://www.intersystems.com/zen/report/definition" ]
{
<report xmlns="http://www.intersystems.com/zen/report/definition"
    name="MyReport" runonce="true">
  </report>
}

XData ReportDisplay [ XMLNamespace = "http://www.intersystems.com/zen/report/display" ]
{
<report xmlns="http://www.intersystems.com/zen/report/display"
name="MyReport">
<body>
<table ongetData="GetCount">
<table orient="row" ongetData="NamesAndAddresses" style="border:1pt solid black">
<parameter fieldnum="1"/>
<item fieldnum="1" >
<caption value="Name"/>
</item>
<item fieldnum="2" >
<caption value="Title" />
</item>
<item fieldnum="3" >
<caption value="Pages" />
</item>
</table>
<parameter value="test" />
</table>
</body>
</report>
}

ClassMethod GetCount(ByRef var As %String, ByRef params)
{
    set count=3
    for i=0:1:count-1 {
        set var(i, 0) = i
    }
}

Method NamesAndAddresses(ByRef var As %String, ByRef params)
{
    if (params(1) = 0) {
       Set var(0,0) = "Alice"
       Set var(0,1) = "Hello"
       Set var(0,2) = 123
    } elseif (params(1) = 1) {
       Set var(0,0) = "Bob"
       Set var(0,1) = "World"
       Set var(0,2) = 456
    } elseif (params(1) = 2) {
       Set var(0,0) = "Charlie"
       Set var(0,1) = "!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
       Set var(0,2) = 789
    }
}

}

Which produces this output:

 

The questions I have:

  1. Is there a way to add breaks between "rows"?
  2. How do I add inside table borders?
  3. How do I give 10% of width to Name/Page/Title and the rest to values?
  4. How do I auto-break long strings into several?
