Calculator and TableApps

You are asked to implement a simple App that creates a table according to user input data (row and column). When you click the "create" button, program will create a table with random integer numbers between 0 and 100 (see the picture as an example). If you have more rows than your device can display then you should able to display rest of the rows with scrolling with your fingers. Also add two more tabs one is for table and the other one remaining issues After the table have been generated (with random numbers between 0 and 100 according to row and column numbers), you may use these table data to make calculation. You should have a "Grade" button on your application and when you click it, each row's averages and related letter marks will be displayed in last two columns on the right side. To set letter grade ranges, you may use Text Fields. For example, you may give "A" marks for numbers between 80 and 90. The supposed Letter marks are: A, B, C, D, F. Each grade range should have one setter Text Field. This application should also have two radio buttons. One of the button is used to sort rows increasing order according to average marks of each row, while another button is used to sort in decreasing order. You should also use one check box. If this check box is checked, all columns' averages calculated at the last row of the table.
