xtable

print console tables. xtable serves as both a class and a command line tool.

• installation
• use the class
• command line from CSV, preformatted table, JSON list to console table, JSON, markdown and more.
• convert table data to Markdown

Installation

`pip install xtable`

run it through xtableorpython -mxtable`

below is a simple introduction for some basic usage.

use the class

from xtable import xtable

data = [
        [1,2,3,4,5],
        [11,52,3,4,5],
        [11,None,3,4,5],
        [11,None,3,None,5],
        ]
hdr = ['c1','c2','c3','c4','c5']

xt = xtable(data=data,header=hdr)
print(xt)

// result :

--------------

xt = xtable.init_from_csv("test/t2.csv")
print(xt)

// result :

data = [

print(xt)

xt2 = xtable.init_from_list(data, xheader="h2,h3")
print(xt2)

     ]
xt = xtable.init_from_list(data, xheader=["h1","h3"])
print(xt.csv())
print(xt.yaml())
print(xt.json())
print(xt.html())

pivot

if we look at the source code, we know class xtable support .pivot() as well,

        if type(js) is list :
            xt = xtable.init_from_json(js,args.header)
            if args.pivot :
                print(xt.pivot())
            else :
                print(xt)

when header has space...

some command output is already a table, only not that decent, eg. as below. xtable will help a little bit. -c told xtable that container id is together while -t told xtable the input stream is already in "table" format.
