Hi Aayush,
Welcome to the CodeRanch!
I would love to help you with your problem, but I am not really sure what you are asking. Can you be more specific? For example what exactly is a 'table' and what do you mean by 'store' it?

The table is a simple data table like a product's name , its weight, colour etc like in a data base and i would like to 'store ' it in a simple .dat file on the hard disk.

You would have to create a format for it, and write that format to the file. Try to avoid the .dat extension, otherwise Windows will think it is a system file.
You might write
Vacuum Cleaner|3.2kg|Red|Can be used as secret weapon
. . . or something similar in each line. The "secret weapon" bit is of course only applicable to Graham Greene fans

If you use a | to split you data make sure that the input doesn't contain that character.

And when using | to split, remember that it's a meta character in regular expressions.
