[reportlab-users] table width / column width

[Chris Schleiermacher]

hi community,

these questionis, which i cannot solve by reading the docu,
are about table with and column width.

if i create a table with two columns, each row
containing only a very short text, the resulting table
has a width of say 3cm.

Q1) how can i force the table to stretch over the complete
    page width?

Q2) how can i force column 1 to have a width X and column 2 
    to have a width Y.


any help would be appreciated

thanks in advance
chris
