I would not use a formal loop constructed with For to accomplish this. The example given above only has three columns. So, deleting the third element is the same as deleting the last element and Most/@data where data is your three column table will do what you want. If your data had a large number of columns then you could do: Join[#[[;;2]],#[[4;;]]]&/@data -- To reply via email subtract one hundred and four
