[R] keeping seperate row.names

I have microarray data with gene names in the first column, gene id in the
second and the expression data in the remaining columns.  When trying use
read.table I get the error, . . . "more columns than column names".  Is
there any way to keep both columns of "names" without having to discard one.
or the other?  The raw data is read from a text file and is in the form
mitogen-activated protein kinase 3	1000_at	946	1928.8	1504.9	722.5	873.9
836.9	1294.3	631.1	606	1126.6	841.2	833.6	689.6	1256.9	685.8	755.3	974.8
where, mitogen-activated protein kinase 3 is the first column of this (tab
delimited) text file and 1000_at is the second column.  I want to keep both
columns as labels.  Is there a way to do that?

I've used: 
test <- read.table("<path>", header=T, sep="\t", row.names=1)
and get the error, more columns than column names.

Many Thanks,
