Writer Table Columns Access via Java API

is is not a bug... the use of writer tables is a little bit different.
the width of a column is not an absolute value, but will be calculated
in realitionship to the width of the table itself. And the width of the
table depends on width of your page, textarea and right/left margins.
so... to change the width of a table-column you need to know a lot of
values and then you can calulate the width of your table istself (a
texttable will be always expand over the hole width of the textarea
minus left and right margin (if set).
Column-width will be specified in the struct
com.sun.star.text.TableColumnSeperator - the array will define all
tableseperators as value based on the total width of the table itself.
your textarea may have a width of 14 cm. Your table should have a width
of 10 cm. So you define a magin left and right of 2 cm.
Now your table will have two colums --- first column should be 3 cm,
second column is now 7 cm.
Your array TableColumnSeperator needs one element - starting from
beginning of table the entry will have the value 3/10*10000 = 3000.
so, always starting from beginning of the table, the width of the Table
is always 10000 (abstarct number, means maybe 100%).
The total width is 10 cm (calculate before), you need 3 cm --so you
get: 3/10 * 10000 - position of your column-seperator.
it is a little bit complicated and I do not have an code-example in java
or ruby, only a german-based basic example. But I hope, you get some
hints so you can search for more informations.
