Only for printing in R: see below for other suggestions.

You are likely to be better off with write.csv(). There _is_ a manual (`R Data Import/Export') about this. (In particular, the default setting for col.names in write.table is not usually what Excel usually expects, and the default separator is space, so you better not have spaces (or for Anne's suggestion, tabs) in the data.)

?round, ?signif, ?format. (Anne's answer applies to printing, not to the table and not to write.table/csv.)
