If the OS is Windows you might want to use two \\ just to be safe
or alternatively use a forward slash instead.

All of that is on a single line, so you could do it with a single
format string
if you prefer.

self.table_file.write('%f\t%f\t%f\t%f\t%f\t%f\n' %
                       self.temp11,self.temp22,
                       self.pyra11,self.pyra22,
                       self.voltage11,self.current11)

Personally I find it easier to read.

To read it back you want to read the line, strip it and then split it
using
a tab as separator.

self.data = tuple(inputfile.readline().strip().split('\t'))
( self.temp11,    self.temp22,
  self.pyra11,    self.pyra22,
  self.voltage11, self.current11 ) = self.data
