Python-PPTX:更改表格样式或向单元格添加边框 [英] Python-PPTX: Changing table style or adding borders to cells
问题描述
我已经开始整理一些代码来获取Pandas数据并将其放入PowerPoint幻灯片中.我使用的模板默认设置为Medium Style 2-Accent 1,因为更改字体和背景非常简单,但是它似乎没有python-pptx的实现部分,该部分允许更改单元格边框.以下是我的代码,可使用任何解决方案. (更改XML或更改模板默认值以填充更好的样式对我来说是不错的选择,但还没有找到有关如何执行操作的有效文档).中号样式4对我来说是理想的选择,因为它恰好具有我要寻找的边框.
I've started putting together some code to take Pandas data and put it into a PowerPoint slide. The template I'm using defaults to Medium Style 2 - Accent 1 which would be fine as changing the font and background are fairly easy, but there doesn't appear to be an implemented portion to python-pptx that allows for changing cell borders. Below is my code, open to any solution. (Altering the XML or changing the template default to populate a better style would be good options for me, but haven't found good documentation on how to do either). Medium Style 4 would be ideal for me as it has exactly the borders I'm looking for.
import pandas
import numpy
from pptx import Presentation
from pptx.util import Inches, Pt
from pptx.dml.color import RGBColor
#Template Location
tmplLoc = 'C:/Desktop/'
#Read in Template
prs = Presentation(tmplLoc+'Template.pptx')
#Import data as Pandas Dataframe - dummy data for now
df = pandas.DataFrame(numpy.random.randn(10,10),columns=list('ABCDEFGHIJ'))
#Determine Table Header
header = list(df.columns.values)
#Determine rows and columns
in_rows = df.shape[0]
in_cols = df.shape[1]
#Insert table from C1 template
slide_layout = prs.slide_layouts[11]
slide = prs.slides.add_slide(slide_layout)
#Set slide title
title_placeholder = slide.shapes.title
title_placeholder.text = "Slide Title"
#Augment placeholder to be a table
placeholder = slide.placeholders[1]
graphic_frame = placeholder.insert_table(rows = in_rows+1, cols = in_cols)
table = graphic_frame.table
#table.apply_style = 'MediumStyle4'
#table.apply_style = 'D7AC3CCA-C797-4891-BE02-D94E43425B78'
#Set column widths
table.columns[0].width = Inches(2.23)
table.columns[1].width = Inches(0.9)
table.columns[2].width = Inches(0.6)
table.columns[3].width = Inches(2)
table.columns[4].width = Inches(0.6)
table.columns[5].width = Inches(0.6)
table.columns[6].width = Inches(0.6)
table.columns[7].width = Inches(0.6)
table.columns[8].width = Inches(0.6)
table.columns[9].width = Inches(0.6)
#total_width = 2.23+0.9+0.6+2+0.6*6
#Insert data into table
for rows in xrange(in_rows+1):
for cols in xrange(in_cols):
#Write column titles
if rows == 0:
table.cell(rows, cols).text = header[cols]
table.cell(rows, cols).text_frame.paragraphs[0].font.size=Pt(14)
table.cell(rows, cols).text_frame.paragraphs[0].font.color.rgb = RGBColor(255, 255, 255)
table.cell(rows, cols).fill.solid()
table.cell(rows, cols).fill.fore_color.rgb=RGBColor(0, 58, 111)
#Write rest of table entries
else:
table.cell(rows, cols).text = str("{0:.2f}".format(df.iloc[rows-1,cols]))
table.cell(rows, cols).text_frame.paragraphs[0].font.size=Pt(10)
table.cell(rows, cols).text_frame.paragraphs[0].font.color.rgb = RGBColor(0, 0, 0)
table.cell(rows, cols).fill.solid()
table.cell(rows, cols).fill.fore_color.rgb=RGBColor(255, 255, 255)
#Write Table to File
prs.save('C:/Desktop/test.pptx')
推荐答案
也许不是很干净的代码,但允许我调整表格中所有单元格的所有边框:
Maybe not really clean code but allowed me to adjust all borders of all cells in a table:
from pptx.oxml.xmlchemy import OxmlElement
def SubElement(parent, tagname, **kwargs):
element = OxmlElement(tagname)
element.attrib.update(kwargs)
parent.append(element)
return element
def _set_cell_border(cell, border_color="000000", border_width='12700'):
tc = cell._tc
tcPr = tc.get_or_add_tcPr()
for lines in ['a:lnL','a:lnR','a:lnT','a:lnB']:
ln = SubElement(tcPr, lines, w=border_width, cap='flat', cmpd='sng', algn='ctr')
solidFill = SubElement(ln, 'a:solidFill')
srgbClr = SubElement(solidFill, 'a:srgbClr', val=border_color)
prstDash = SubElement(ln, 'a:prstDash', val='solid')
round_ = SubElement(ln, 'a:round')
headEnd = SubElement(ln, 'a:headEnd', type='none', w='med', len='med')
tailEnd = SubElement(ln, 'a:tailEnd', type='none', w='med', len='med')
