NOTE

 Column and Row are colored with a coded color ‘Cxyz’.

    Where C: Color (coding must begin with C)

                 X: Color Number

                 Y: Bold

                 Z: Inverse.

 The Selection Screen will be as follows. 

     

In the Selection screen if we enter only the Column Number and color the whole column will be colored as follows.

 

In the Selection screen if we enter only the row Number and color, the whole column will be colored as follows.

   

 In the Selection screen if we enter both the Row number and the Column Number then that particular cell will be colored as follows (this color is not picked from selection screen, it is already written in the program itself)
