How to add lines between specific rows and col's in a table?

Let's say I have this matrix:

    M     1    2     3     4     5     6     7     
    _     _    __    __    __    __    __    _     

    M     0     0     0     0     0     0     0   
    M     0     0     0     0     0     0     0    
    M     0     0     0     0     0     0     0      
    M     0     0     0     0     0     0     0    
    

How can I draw a horizontal line between this first and second row?

And a vertical line between columns 6 and 7?

is this possible?

if this involves downloading a package, where can I do so?

Thank you,

No, it is not possible to display horizontal and vertical lines in a table or in a uitable.

You could add a column of characters "|" to simulate a dashed vertical line but since your table contains numeric values you cannot use the same approach to add a horizontal line but you could add a horizontal row of NaN values for a visual separator.

@Amanda another idea to visually group columns of a table is to use nested tables.

T1 = array2table(rand(10,3),'VariableNames',{'a1','a2','a3'}); 
T2 = array2table(rand(10,3),'VariableNames',{'b1','b2','b3'});
T = table(T1, T2,'VariableNames',{'Group1','Group2'})

T = 10×2 table
                 Group1                              Group2             
       a1          a2          a3          b1          b2          b3

Thank you! I hope they can do something for horizontal lines one day too.
