Who was the first person to introduce logthrim tables?

The first person to introduce logarithmic tables was John Napier, a Scottish mathematician, in the early 17th century. He published his work on logarithms in 1614 in a book titled "Mirifici Logarithmorum Canonis Descriptio." Napier's invention significantly simplified calculations by transforming multiplication and division into addition and subtraction, paving the way for further developments in mathematics and computation.
