Question

在挖掘Table类和Text类之后，我设法生成一个宽度和高度不相等的表，这取决于单元格内部文本的大小（我借用matplotlib示例）：

data = [[  66386,  174296,   75131,  577908,   32015],

columns = ('Freeze', 'Tornados', 'Flood', 'Quake', 'Hail')
n_rows = len(data)
y_offset = np.array([0.0] * len(columns))
cell_text = []
for row in range(n_rows):
    y_offset = y_offset + data[row]
    cell_text.append(['%1.1f' % (x/1000.0) for x in y_offset])
cell_text = np.array(cell_text)
cell_colors = np.tile(np.ones_like(cell_text,float)[...,None] -0.5
                      ,(1,1,3))
fig = plt.figure()
axes = fig.add_subplot(111)
the_table = axes.table(cellText=cell_text,
                      colLabels=columns,
                        cellColours=cell_colors,
                      loc='center')
#he_table.properties()['celld'][0,0].get_text().set_fontweight(1000)
the_table.auto_set_font_size(False) 
the_table.scale(3, 3) 
the_table.set_fontsize(20)
table_prop = the_table.properties()
#fill the transpose or not, if we need col height or row width respectively.
rows_heights = [[] for i in range(len([cells for cells in 
                                     table_prop['celld'] if cells[1]==0]))]
cols_widths = [[] for i in range(len([cells for cells in 
                                     table_prop['celld'] if cells[0]==0]))]
for cell in table_prop['celld']:
    text = table_prop['celld'][(0,0)]._text._text

    bounds = table_prop['celld'][cell].get_text_bounds(fig.canvas.get_renderer())
    cols_widths[cell[1]].append(bounds[2])
    rows_heights[cell[0]].append(bounds[3])

cols_width = [max(widths) for widths in cols_widths]
rows_height = [max(heights) for heights in rows_heights]
for cell in table_prop['celld']:
    bounds = table_prop['celld'][cell].get_text_bounds(fig.canvas.get_renderer())                                            
    table_prop['celld'][cell].set_bounds(*(bounds[:2]+(1.*cols_width[cell[1]],
                                                       1.1*rows_height[cell[0]],
                                                     )))


plt.axis('off')
plt.show()

结果如下：

虽然具有文本的单元格正确呈现相应列的宽度和高度，但具有数字的单元格无法实现。解决这个问题的一个明显方法是将cols_width和rows_height乘以大于1.是否有人知道为什么会发生这种情况并提供解决方案？

Answer 1

由于文字位于x = l + (w * (1.0 - self.PAD)) 你需要让你的格子2*self.PAD更大。对于默认值self.PAD = 0.1，最后一行看起来像

table_prop['celld'][cell].set_bounds(*(bounds[:2]+(1.2*cols_width[cell[1]], ...)))

Matplotlib：表：不等长度的列和行
