Résumé table job post end date become the next job's start date

Hello, community. Imm attempting to create a résumé table. I want to be able to add jobs that have the following fields. ‘Title’ ‘Start’:formula ‘End’:formula ‘months worked’:numeral. The first entry the job start is hardcoded and the job ended is calculated by adding the months worked to the job start. The second entry job start is a reference to job end from the previous entry. Hope that makes sense.
