Python：使用文本表将列表打印为表格

Question

我想使用texttable将列表打印为表格。

这是我的代码：

col_types = ['t']
col_names = ['sessions/week']
col_align = ['r']
weeks_result = []
for i in range(1,53):
    col_types.append("t")
    col_names.append(str(i))
    col_align.append("r")
table = Texttable()
table.set_deco(Texttable.HEADER)
table.set_cols_dtype(col_types)
table.set_cols_align(col_align)
table.add_row(col_names)

import pdb; pdb.set_trace()
for area, results_per_week in areas_weeks_dic.items():
    weeks_result.append(area)
    for i in range(1,53):
        weeks_result.append(results_per_week[str(i)])
    print weeks_result
    table.add_row(weeks_result)
    weeks_result = []

print table.draw()

如您在上面看到的，我有一个断点，我已经使用该断点打印一些数据供您查看，基本上每行中都有53个元素。 这个基本代码以某种方式给了我一个我无法解读的非常奇怪的错误。 跟踪在下面的末尾提供。 我究竟做错了什么？ ValueError的原因是什么？

Answer 1

我设法通过反复试验解决了这个问题。 由于我有一张大桌子(+50 or so columns)因此如果没有每个单元格的正确宽度信息，就无法打印它。

一旦我提供了一个具有每个单元格宽度的数组，它就可以立即工作。

table.set_cols_width(col_width)
