I need to import a txt file, that contains a large number of columns
(separated by TAB) ,as follows:
1)jump the first two lines of *.txt
2)columns widths are [10 10 10 10 10 19 15....(from this
point =15 for every column)
3)import columns from 1 to 240 in sheet1
import columns from 241 to 276 in sheet2
...and so on

I search throgh google and NG reading a lot of suggestion, but still I can't
do this (important) thing...:-(

hoping this could help, here are the 3rd line of txt files (from whic I need
to do import)

0,000028 0,000032 0,000047 0,000095 0 0,00000838 0,00000052 0,00000319
