我已經開始整理一些代碼來擷取Pandas資料并将其放入PowerPoint幻燈片中.我使用的模闆預設為中等樣式2 – 重音1,這很好,因為更改字型和背景相當容易,但似乎沒有實作python-pptx的部分允許更改單元格邊框.以下是我的代碼,可以解決任何問題. (改變XML或更改模闆預設設定以填充更好的樣式對我來說是個不錯的選擇,但是沒有找到關于如何做的好文檔).中等風格4對我來說是理想的,因為它具有我正在尋找的邊界.
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')
解決方法:
也許不是真正幹淨的代碼,但允許我調整表格中所有單元格的所有邊框：
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')
