How to align and set color at the same time inside a cell with python-docx - python-docx

Question

I am trying to make a table with python-docx.
This is my desire output:
¡--OK(bold)--¡--MIDDLE(in red)--¡----RIGHT¡
And this is what I get:
¡--OK(bold)--¡MIDDLE(in red)----¡RIGHT----¡
The code that I use is:
from docx import Document
from docx.shared import RGBColor
from docx.enum.text import WD_ALIGN_PARAGRAPH
document = Document()
table = document.add_table(rows=1, cols=3, style='Table Grid')
fila = table.rows[0].cells
# First cell: OK in bold
texto = 'OK'
dentro = fila[0].paragraphs[0]
dentro.add_run(texto).bold = True
dentro.alignment = WD_ALIGN_PARAGRAPH.CENTER
# Second cell: Middle in red
texto = 'MIDDLE'
dentro = fila[1].paragraphs[0].add_run(texto)
dentro.alignment = WD_ALIGN_PARAGRAPH.CENTER
font = dentro.font
font.color.rgb = RGBColor(255,0,0) # Red
# Third cell : Right
texto = 'RIGHT'
dentro = fila[2].paragraphs[0]
dentro.add_run(texto)
dentro.aligment = WD_ALIGN_PARAGRAPH.RIGHT
document.save('demo.docx')
I have two issues: First one is that I do not get the correct alignment in the middle cell when I add the color issue. Second one is that in cells after the wrong output of middle one, the alignment does not seem to work. How can I fix it? Do I have to wait until next version (actual 0.8.10)? Thanks,

Answer 1

Your code for the middle cell is different. You assign the new run to dentro rather than the paragraph. This causes the alignment value to be assigned to the run where it does nothing.
Change:
dentro = fila[1].paragraphs[0].add_run(texto)
to:
dentro = fila[1].paragraphs[0]
run = dentro.add_run(texto)
font = run.font
font.color.rgb = RGBColor(255, 0, 0)
I'm not sure how to account for the RIGHT alignment not "taking" on the third cell; I would make this fix and then see how you go.
