Use the integral expression of the Euler Mascheroni constant:
you'll obtain:

Maybe I missed your initial question:
Perhaps you mean that you don't see some Laplace transformed in the standard tables. The reason is that some of them, don't exist (it has been already commented by chisigma). In other cases, (for example, for the logarithmic funcion) we need some previous results.
