Is it possible in JCE too - with standard commands and without complex modifications?
No, this can only be done with css. You could for example create a css class in your template stylesheet, which you can then apply to the table cell, eg:
td.rotate-text,
th.rotate-text {
transform: rotate(90deg);
white-space: nowrap;
text-align: center;
vertical-align: middle;
}

Just because you're not paranoid doesn't mean everybody isn't out to get you.
