I have been wondering quite a long , that how the percentage width in table cells work in HTML.

Case 1: No table width specified, single row and columns are not given full space

    

        
mango
        
apple
    

Case 2: No table width specified,single row and columns are given full space

    

        
mango
        
apple
    

Case 3: No table width specified,single row and columns are given more than 100% space

    

        
mango
        
apple
        
guava
    

Case 4: No table width specified, multiple rows specified and columns are giving following percentage configurations

    

        
mango
        
apple
        
guava
    
    

        
papaya
        
pomengrante
    

Their outputs I am not able to correlate , please help me in this
