Rendering tables in jupyter notebook

[Gaurish Telang]

I want to create a neat table of the factorization of several polynomials of the form in the ring Z/3Z [x].

This is my code, which I am using inside of a Jupyter notebook that works as expected:

R = IntegerModRing(3) 
x = PolynomialRing(R, 'x').gen()

rows  = []
for k in range(1,10):
    f = x^k - 1
    factor = f.factor()
    rows.append((f,factor))

table(rows, header_row=["Polynomial ", "Factorization"], frame=True)

However, the output produced is ugly and looks like the one in the attachment; it leaves a lot of space on the right but the factorization is spread across multiple rows. How can I ask Sage to place each factorization in the right column on a single line.

Also is it possible for me to write for various powers of in latex in place of . i.e. I want to write -1 wherever there is a 2 in the left column. Sure I can do this with print, but the output won’t be Latex rendered.

Both the display in a console and the LaTeX display given by `view` are single-lined. I can reproduce your problem in Jupyter ; therefore, I think that the question should be directed to a Jupyter-centered mailing list, newsgroup, forum or whatever...

I cant't make head or tail of this gibberish. Could you rephrase ?

HTH,

Thanks! I will ask on the Jupyter mailing list. 

Also is it possible for me to write  for various powers of  in latex in place of . i.e. I want to write -1 wherever there is a 2 in the left column. Sure I can do this with print, but the output won’t be Latex rendered.

I apologize that it was terribly worded.   It was just a dumb question that occured while trying to understand how the `table` function outputs data into a jupyter notebook cell. 

I basically wanted the left hand-side to contain in place of for different values of  i.e. in place of   

  in place of and so on.  I know of course -1 and 2  are identical in Z/3Z, but I was wondering if there was a  way to display (-1) in place of 2 while using the `table` command and working Z/3Z.

I doubt it : Sage is strngly opinionated (you could say asinine) about its presentation choices, and, for example, systematically rewrite `1/sqrt(2)` as `sqrt(2)/2`. Even if you sacrifice a goat ;-)...

I just wanted to add, I noticed that the bad alignment goes away if I remove the header_row argument in the call to table

Thus, I get the expected output with the following code (without the column names of course): see attachment.

R = IntegerModRing(3) 
x = PolynomialRing(R, 'x').gen()

rows  = []
for k in range(1,10):
    f = x^k - 1
    factor = f.factor()
    rows.append((f,factor))

table(rows, frame=True)

I wonder how the header_row argument messes up the alignment for Latex in the other rows of the table.

Note it still doesn't align left if you use table(rows, frame=True, align='left')

I'd guess that the header_row is used to determined the column width, without checking the rest of the table.

(That's how it works in LaTeX, anyway.)

PS. I also notice  that documentation for table() is rather patchy, and does not even tell you about the

possibility of having anything except True/False/None in the header row. (There are examples there thate tell

that it's possible)...
