I have the tables tblEmployees and tblProjects. tblProjects has one column called Percentagetime, to hold the percentage of time by an employee for a project.

I have the tables tblEmployees and tblProjects. tblProjects has one column called Percentagetime, to hold the percentage of time by an employee for a project.
My Question : Why should we introduce a 3rd table called
tblProjectsAndEmployees?
tblProjectsAndEmployees will have
1)EmployeeNumber(PrimaryKey in tblEmployees)
2)ProjectNumber(Primary key in tblProjects)
3)PercentageTime
Having only the tblEmployees and tblProjects is not sufficient?
Kind Regards,
