[reportlab-users] Format cells inside table

[Chris Else]

Hi Jakob,

Using your example and the code at:
http://www.blog.pythonlibrary.org/2010/09/21/reportlab-tables-creating-tables-in-pdfs-with-python/

I have a solution that might work for you.

Kind regards

Chris


from reportlab.lib import colors
from reportlab.lib.pagesizes import letter
from reportlab.platypus import SimpleDocTemplate, Table, TableStyle

doc = SimpleDocTemplate("simple_table.pdf", pagesize=letter)
# container for the 'Flowable' objects
elements = []

table_data = [['Firstname', 'Lastname', 'Points']]
table_style = [('TEXTCOLOR', (0,0), (-1, -1), colors.black),
  ('INNERGRID', (0,0), (-1,-1), 0.25, colors.black),
  ('BOX', (0,0), (-1,-1), 0.25, colors.black)]

data = [['Jakob', 'Moller', 5],
  ['Anna', 'Moller', 10],
  ['Another', 'Person', 1]]

row_number = 1

for forename, surname, points in data:
  if points > 5:
    cell_colour = colors.green
  elif points < 5:
    cell_colour = colors.red
  else:
    cell_colour = colors.yellow

  table_data = table_data + [[forename, surname, str(points)]]
  table_style = table_style + [('BACKGROUND', (0,row_number), (-1,
row_number), cell_colour)]

  row_number = row_number + 1

t=Table(table_data)
t.setStyle(TableStyle(table_style))
elements.append(t)
# write the document to disk
doc.build(elements)
