    public addRowRemoveRow(){
        allAccs = new List<Account>();
        Account acc1 = new Account();
        allAccs.add(acc1);
    }

    public void addRowMethod(){
        Account acc1 = new Account();
        allAccs.add(acc1);
    }

    public void removeRowMethod(){
        integer count = allAccs.size();
        system.debug('size----->'+count);
        allAccs.remove(count--);
    }

    public void saveMethod(){
        insert allAccs;
        clearMethod();
    }



    public void clearMethod(){
        integer finalCount = allAccs.size();
        allAccs.clear();
        for(integer i=0;i<finalCount;i++){
            Account acc1 = new Account();

For delete the selected row you can use wrapper class. It is more better approach. There is a sample given in this link you can check here.

if you want to delete permanently on edit click then you can use map in controller, pass record id using param in the controller and then delete the record using DML. You can take help from here

Hope it will solve your problem.
