Python PPTX：如何改变表（Tabel）边框颜色？默认颜色是白色

Question

我想实现，从图片1到图片2的边框效果，即实现由无色到黑色的转变；我添加table语句：blank_slide_layout = self.prs.slide_layouts[4]
slide = self.prs.slides.add_slide(blank_slide_layout)
shapes = slide.shapes
inputpd = inputpd.sort_values('激励点及方向')
DataListNumber = len(inputpd.index)
rows = DataListNumber + 2
cols = len(self.vtf_sum_header) -2
left = Cm(1.51)
top = Cm(3.56)
width = Cm(26.68)
height = Cm(12.62)
table = shapes.add_table(rows, cols, left, top, width, height).table
