USA new federal tax withholding

[spyshot]

If the personal deductions have been repealed, why are the new federal tax withholding calculations still taking into account the allowances on the employees' W-4? I'm referring to page 45 of publication 15 (2018). I'm very confused here.

Thanks for any insight you can give.

Using them can result in more or less withheld.

thanks for the response, but the questions still stands.

are they taking into account that the child tax credit and standard deductions doubled?

The answer still stands.

the question was not how do i raise or lower the withholding, the question is why are they considering allowances when calculating the withholding amount when the personal deduction has been repealed?

Answer still stands.
