Plain text does not wrap - this is a performance optimisation for the 
large numbers of tables which display (e.g.) financials.  To get it 
wrapping, put a flowable or a list of flowables in the "table cell" e.g.

Not tested but here's the idea
  row1 = [   #this has two elements, each a list of flowables.
      Para("My heading", style="heading"),
    ],   #left cell contains one heading para

    [#right cell can hold multiple paragraphs
     Para("My body first para", style="body"),
     Para("My body first para", style="body"),
     Para("My body first para", style="body")


tableData = [row1, row2, row3]

table = BlockTable(tableData, style=MyTableStyle)

This sucks a bit in Python but it's way easier in RML as we're all 
trained to parse <table>,<tr>,<td> in our heads these days.  You might 
find it's a good idea to scan the table sample files in the RML suite 
here, and then mentally translate those patterns back into Platypus - 
the objects correspond pretty closely to what you'd expect and will make 
the above seem clearer.  See example 8 here:
