datayouhave = rand(8, 5); % replace this with your data
t = array2table(datayouhave, "VariableNames", ["Maths", "Physics", "Politics", "Economy", "English"]);
name = ["AAA", "AAA", "AAA", "BBB", "BBB", "BBB", "CCC", "CCC"]';
t = [array2table(name) t];
t
t = 8×6 table

Thanks for theResponse but iam getting error "t = array2table(datayouhave, "VariableNames", ["Maths", "Physics", "Politics", "Economy", "English"]);"
Error using table.init (line 380)
The VariableNames property must be a cell array, with each element containing one
nonempty character vector.
Which MATLAB version are you using?
Try
datayouhave = rand(8, 5); % replace this with your data
t = array2table(datayouhave, 'VariableNames', {'Maths', 'Physics', 'Politics', 'Economy', 'English'});
name = {'AAA', 'AAA', 'AAA', 'BBB', 'BBB', 'BBB', 'CCC', 'CCC'}.';
t = [array2table(name) t];
t
t = 8×6 table
name Maths Physics Politics Economy English _______ ________ ________ ________ _________ ________ {'AAA'} 0.057449 0.99295 0.93589 0.88883 0.54624 {'AAA'} 0.20587 0.3941 0.058401 0.93182 0.29469 {'AAA'} 0.6748 0.18482 0.71994 0.48408 0.84695 {'BBB'} 0.51505 0.60256 0.21766 0.99488 0.17571 {'BBB'} 0.32222 0.16554 0.039902 0.64758 0.82738 {'BBB'} 0.95771 0.056249 0.86953 0.94728 0.085409 {'CCC'} 0.82799 0.75418 0.95384 0.0025524 0.52635 {'CCC'} 0.72661 0.97953 0.73226 0.92357 0.97658

You cannot create that kind of table in MATLAB.
In order to have a row name span multiple rows, you will need to create a table with three rows and two variables. The first variable will be the Name. For each row, the second variable must be a complete table.
M = round(randn(15, 5), 1)
M = 15×5
-0.2000 -0.5000 -0.1000 -0.9000 1.6000 2.0000 0.5000 0.6000 1.1000 -0.1000 0.4000 1.1000 -0.7000 -1.1000 1.0000 0.1000 0.5000 2.1000 0.8000 -0.4000 0.7000 1.1000 0.5000 -0.4000 1.1000 -0.4000 -0.4000 0.8000 1.5000 -0.7000 -0.7000 -0.2000 0.6000 0.4000 0.6000 0 0.7000 -0.3000 -0.4000 -0.6000 -0.9000 -1.3000 -2.0000 2.4000 -2.2000 -0.4000 -0.6000 -0.7000 1.1000 1.1000
varnames = ["Maths", "Physics", "Politics", "Economy", "English"];
T1 = array2table(M(1:5,:), 'VariableNames', varnames);
T2 = array2table(M(6:10,:), 'VariableNames', varnames);
T3 = array2table(M(11:15,:), 'VariableNames', varnames);
names = ["Ramu"; "Rihith"; "Swarmy"];
Output = table('Size', [3 2], 'VariableTypes', ["string", "table"], 'VariableNames', ["Name"; "Marks"]);
Output.Name = names;
Output.Marks = {T1; T2; T3};
Output
Output = 3×2 table
Name Marks ________ ___________ "Ramu" {5×5 table} "Rihith" {5×5 table} "Swarmy" {5×5 table}
Output.Marks{1}
ans = 5×5 table
Maths Physics Politics Economy English _____ _______ ________ _______ _______ -0.2 -0.5 -0.1 -0.9 1.6 2 0.5 0.6 1.1 -0.1 0.4 1.1 -0.7 -1.1 1 0.1 0.5 2.1 0.8 -0.4 0.7 1.1 0.5 -0.4 1.1
So you can construct the table, but it will not display nicely.
