If you want the high-quality typesetting, then of course you should use 
TeX.

Presumably you have tried to read the lines from within a tabular
environment, which is then just taking place within the 1st cell.

An easier way to read data from a file, into a table,
is to preprocess (a copy of) the data-file to contain all
of the markup for the table. In practice this can be done
quite easily using a spreadsheet, allowing you to insert
columns of & and \cr characters.

Then use \input to read the preprocessed data as normal TeX source
containing the whole table, rather than \read it line-by-line
and trying to program how each piece should be handled.
