i.e. not
fdisk /dev/sda; cryptsetup create xxx /dev/sda1
but vice versa
cryptsetup create xxx /dev/sda ; fdisk /dev/mapper/xxx
is it allowed?
fdisk cryptsetup partition-table

It's possible, but might need additional steps (kpartx) to make those partitions available.
parted /dev/mapper/cryptsda
kpartx -a /dev/mapper/cryptsda
mount /dev/mapper/cryptsda1 /mnt/firstpartition
Most people just use LVM instead, of course LVM also needs VG/LV to be enabled first, but this is usually handled for you by whatever init system you use.
However, you should still partition the raw drive regardless, otherwise there is a high risk of data loss. A seemingly unpartitioned drive is fair game for all partitioners, installers, etc.
So usually it's /dev/sda » /dev/sda1 » cryptsetup/LUKS » LVM » filesystem.
