One can do

lw(\n(.lu/10u) lw(\n(.lu*9u/10u).

This is possible because the content of w() is interpreted
by troff, not by tbl. Unfortunately it only works with GNU
tbl and Heirloom tbl because traditional tbl variants have
a limit of 10 characters inside w(). A workaround to make
this fully portable is

.nr %1 \n(.lu/10u
.nr %9 \n(.lu*9u/10u
lw(\n(%1u) lw(\n(%9u).
