One quick way to do it is to read it in as a string and then use ImportString [] to sort it out.
TestA.Txt:
1 2 3
4 5 6
In= mList=Import["c:\\testa.txt"];
In= mList=ImportString[mList,"Table"]
Out= {{1,2,3},{4,5,6}}
OR
In= ReadList["C:\\testa.txt", Number, RecordLists -> True, WordSeparators-> {" ", "\[Backslash]t"}, RecordSeparators -> {"\r\n", "\n", "\r"}]
Out= {{1,2,3},{4,5,6}}
Note: Don't leave Number specifier out! Also, here is the URL in the help system that I used (if it helps):

Is there a way to read a file with a user specified word separator and record separator, such that the result is a list of lists of words?
For example, a file containing "1 2 3\n4 5 6" would become {{1,2,3}, {4,5,6}}.
Import does almost exactly what I want, although I can't figure out how to change the word and record separators.
In particular, I have a file where word separators are tab characters, but the data themselves have spaces. Therefore, Mathematica's default word separator of whitespace does not work.
