How do I define a style for even and odd rows of a table (python reportlab) -

i have print report may hundreds rows in length. particularity each item's content should printed on 2 lines. lines have specific style.

sample :

line 1 : first header line  line 2 : second header line  line 3 : name , adress line 4 : birth date , gender, hobbies  line 5 : name , adress line 6 : birth date , gender, hobbies  ... 

i use table handle per page content.

in style definition, have this:

('fontsize',(0,2),(-1,-1),18) 

but want style applies rows , style 1

('fontsize',(0,2),(-1,1),12) 

applies odds rows.

the best 2 styles applies on whole table except first , second row contains header of table.

you can having code generates table style based on row number. reportlab have built-in feature automatically alternating background colors rows , colors (look rowbackgrounds , colbackgrounds in user manual), arbitrary styles you'll have custom following looping through data rows.

table_style = [...]  i, row in enumerate(table_rows):   if % 2 == 0:     table_style.append(('fontsize',(0,i),(-1,i),18))   else:     table_style.append(('fontsize',(0,i),(-1,i),12))  my_table.setstyle(tablestyle(table_style))
