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.

Ran in:
@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 ________________________________ ________________________________ 0.16812 0.28017 0.95857 0.093635 0.28161 0.79661 0.033868 0.52494 0.7073 0.3808 0.49159 0.57436 0.12971 0.011963 0.076642 0.79273 0.39691 0.96186 0.38691 0.96205 0.60905 0.79519 0.97328 0.27091 0.5583 0.72393 0.25809 0.32267 0.84849 0.94615 0.71782 0.26672 0.2257 0.44711 0.88207 0.53404 0.85151 0.86651 0.88928 0.090695 0.50398 0.066152 0.26138 0.80449 0.68335 0.0047975 0.11711 0.68808 0.050793 0.49833 0.28434 0.67507 0.8772 0.73168 0.24256 0.84214 0.73277 0.15012 0.57785 0.15575

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