mutt destroys allignment of file alligned by column command unix

Question

I have a well aligned csv file.

• That was generated using the command column -s, -t < myFile >myFormattedFile. It looks as expected.

• Now I want the same to be displayed in gmail body. And I use command mutt my@email -s my_subject < myFormattedFile

• However in gmail formatting gets destroyed. Searching on the web I found that i can set set text_flowed=yes in the muttrc. But even that doesnt work. -If I attach the file using -a option in mutt, then formatting is preserved (opening the attachment). Also note that if the attached file given the name myFormattedFile.csv then google opens it with spreadsheet with destroyed formatting. This last point is just my additional observation.
