Remove blank columns from a tab delimited text file

Hello,

I have some tab delimited files that may contain blank columns. I would like to delete the blank columns if they exist. There is no clear pattern for when a blank occurs.

I was thinking of using sed to replace instances of double tab with blank,
sed 's/\t\t//g'

All of the examples I have seen are two consecutive blanks columns. I don't believe that there will be instanced of more than two blank cols, but it's hard to say. It would be nice to have code that was more generic.

How about: tr -s '\t' < inputfile > outputfile

One, two, three four, or three hundred tabs in a row will become one tab.
