这是一个创建于 1424 天前的主题，其中的信息可能已经有所发展或是发生改变。
临近期末，我需要打印一些计算题,给班上的学生练习一下.
当我把计算题生成完了之后，再生成 pdf 文档打印。我没有用 excel，因为在其它电脑上使用可能会出现打印预览的问题。所以选择了 reportlab 生成 pdf 把格式固定下来，打印也方便了很多。
from reportlab.platypus import Table,TableStyle
使用这 table 生成表格，tableStyle 调整表格样式。
当我使用默认的格式是这样的:
# Title
elements = []
# Table
table_date = [
['98 + 12= ','1 + 3 =','3 * 9 =','81 / 9 ='],
]
table_style = [
('GRID',(0,0),(-1,-1),1,colors.black),
('FONTSIZE',(0,0),(-1,-1),13),
('ALIGN',(0,0),(-1,-1),'LEFT'),
# ('FONTNAME',(0,0),(-1,-1),'mysh')
]
mytable = Table(table_date)
mytable_style = TableStyle(table_style)
mytable.setStyle(mytable_style)
elements.append(mytable)
doc = SimpleDocTemplate(
"tmp.pdf",
pagesize = A4,
)
doc.build(elements)
表格和字体就太小了，我先把表格的高度和宽度作为调整：
#mytable = Table(table_date)
mytable = Table(table_date,colWidths=125,rowHeights=32)
指定了高度和宽度。
现在宽度和高度差不多了，我继续调整字体大小就出问题了。
table_style = [
('GRID',(0,0),(-1,-1),1,colors.black),
('FONTSIZE',(0,0),(-1,-1),13),
('ALIGN',(0,0),(-1,-1),'LEFT'),
# ('FONTNAME',(0,0),(-1,-1),'mysh')
]
我把这个 ('FONTSIZE',(0,0),(-1,-1),13),的 13 修改成 20 。
table_style = [
('GRID',(0,0),(-1,-1),1,colors.black),
('FONTSIZE',(0,0),(-1,-1),20),
('ALIGN',(0,0),(-1,-1),'LEFT'),
# ('FONTNAME',(0,0),(-1,-1),'mysh')
]
如图所示，算式直接跑出来了。 有知道的大佬帮下忙呗。 下面是所有代码和预览图，刚学，写的比较乱。
