[scribus] Importing tables

Hello,
Many thanks for all your answers.
1) I go to http://wiki.scribus.net and found at least two scripts for
importing csv files to a table. However, neither was the Importcsv2table
which I found with the 1.4.3 version of Scribus! Moreover, I was a little
lost. So, as I do not know if it is allowed to add a file to a message, I
append my script here after.
The code has just to be copied to a text file. I called it
csv2table.py and put it in the "share/scripts/" directory of Scribus. Then
it is usable from inside Scribus.
Any feedback/comment will be welcome.
2) In most of the case I will import a table to Scribus, I want that the
text in each cell is centered horizontally and vertically. The horizontal
centering is easy to do automatically by using a style. For the automatic
vertical centering I do not have found a solution at present time. I just
allow setting the top distance for the texts. However, the number of lines
of the texts is not always the same and the height of the cells also is not
always the same. So the top distance should be calculated taking into
account the effective height of the text in each cell.
So my question: is there an API or function allowing getting the
height of the entire text in a textbox? Any help will be welcome.
Regards,
Jean-Paul

My csv2table.py script
--------------
#!/usr/bin/env python
# -*- coding: utf-8 -*-
"""
ABOUT THIS SCRIPT (modified by J.-P. Gendner June, 15 2014):
Import CSV data files as tables into Scribus
1. You may create a style to be applied to all cells of the table
2. Create a frame at the position (upper left corner)
and of the size (height and width) you want for your table
3. Make sure it is selected
4. Execute this script:
You will first be prompted for the csv data filename.
-> The number of columns and row will be displayed.
You will then be prompted for the width of each column in mm.
-> The default value given is calculated to respect the width of the
table.
Then you will be prompted for the height of each row.
-> The default value is calculated to respect the height of the table.
Then you may enter the style name you want to be applied to each cell.
Finally, you may enter the Top distance for all text.
5. The data from the csv file will be imported and a table of
textboxes will be drawn on the page.
LIMITATIONS:
In Scribus versions 1.3.5svn, when the script ends, you cannot
adjust text, colors, and line features for a group, whereas in 1.3.3.x,
all of these can be done without ungrouping.
HINTS:
Postgresql:
You can easily create a CSV file with a Postgresql database. From
Postgresql,
toggle unaligned output with the '\a' switch, then activate a comma as
a separator with '\f ,' (without apostrophes). Send output to a file
with '\o myfile.csv', then query your database.
Sqlite3:
You can use "sqlite3 -csv" in the command line or ".mode csv" in sqlite's
interactive shell.

Bonsoir Jean Paul,
You could share your script using the http://wiki.scribus.net
Register and create a new page with your script
and link it in the appropriate page,
maybe the one mentionning the original script.
It requires using some wiki syntax.
OK ?
Another way would be to put in in the bug tracker,
specially if you think your version improves the old one and could replace
it.
http://bugs.scribus.net
Another way would be to put in on github...
Comme tu veux !
JLuc
