[SOLVED]Question about Process txt file

Hello,

I have "txt" file like this:
1 3 9 13 23 25 34 36 38 40 52 54 59 63 67 76 85 86 90 93 98 107 113
2 3 9 14 23 26 34 36 39 40 52 55 59 63 67 76 85 86 90 93 99 108 114
2 4 9 15 23 27 34 36 39 41 52 55 59 63 67 76 85 86 90 93 99 108 115
1 3 10 15 23 25 34 36 38 41 52 54 59 63 67 76 85 86 90 93 98 107 113
2 3 9 16 24 28 34 37 39 40 53 54 59 63 67 76 85 86 90 94 99 109 114
... ...

what I want is read this file like I use "ReadCSV" to read a csv file. After read this file, I want get a table like:
             att1  att2 att3  att4  ... ...
ROW 1: 1       3     9     13    23 25 34 36 38 40 52 54 59 63 67 76 85 86 90 93 98 107 113
ROW 2: 2       3     9     14    23 26 34 36 39 40 52 55 59 63 67 76 85 86 90 93 99 108 114
... ...

I think it is the same thing as read a CSV file by "ReadCSV" but , the probleme is the format of my file is "txt". I used the "Read Document", but I don't know
how can I generate a "table" with "attribute, label ..."

The reason why I ask this question is that I am doing a project to add a algorithm about (association rule) in rapidminer, my adviser require me use a "more general format file" like  "txt file" as my Data source. after read this "txt" file, I can get  "exampleSet"s to do flowing thing I think  ???.

Thanks in advance!
