Is it possible to give title for a table i have displayed as below
If i wanted to give a title 'My Table', how to give it?
Details = [38,71,176,124,93;...
43,69,163,109,77;...
38,64,131,125,83;...
40,67,133,117,75;...
49,64,119,122,80];
T = array2table(Details,...
'VariableNames',{'Age' 'Height' 'Weight' 'BP_High' 'BP_Low'},...
'RowNames',{'Smith';'Johnson';'Williams';'Jones';'Brown'});
disp(T)

You could effectively give a title to a table by nesting the table within another single-column table that contains the title.
Details = [38,71,176,124,93;...
43,69,163,109,77;...
38,64,131,125,83;...
40,67,133,117,75;...
49,64,119,122,80];
T = array2table(Details,...
'VariableNames',{'Age' 'Height' 'Weight' 'BP_High' 'BP_Low'},...
'RowNames',{'Smith';'Johnson';'Williams';'Jones';'Brown'});
T = table(T,'VariableNames',{'My Table'}); % Nested table
disp(T)
However, now you'll have to index the table differently. For example, to access Height,
T.('My Table').Height
Or to access the 3rd row,
T.('My Table')(3,:)
or you could un-nest the table,
T = T.('My Table');

Good point. Though for general variable names you need r2019b or later, and I think the user is using a release before that (but I could be misremembering)

There isn't much utillity in assigning a table title in Matlab. It requires additional steps when accessing the data and doesn't offer any additional benefits in referencing tables. If the table is to be displayed in a text file, the title could be added within the file after exporting it. If you want to display the title in the command window and identify the table by some kind of table name, you could always use an fprintf command to display the title name just before displaying the table.

No, table() is designed for programming, not for display purposes.

Yes, it is possible to give a title to a table.
filename = fullfile(matlabroot, 'toolbox', 'matlab', 'datatypes', 'tabular', '@tabular', 'disp.m');
edit(filename)
Look close to the end of the first function, somewhere near line 265. You will see code that looks like
[varChars,nestedVarChars,underlines] = getVarNamesDispLines();
disp(char(varChars));
That is the line of code that displays the variable names, and the next few lines of code display headers and then the content. By this point in the code, everything has been computed and put into arrays for later display.
So just before that getVarNamesDispLines(), insert your code that figures out the title to use for the table, and then display it.
Last I recall you were using R2017a. If you were using R2018b or later you could use addprop() https://www.mathworks.com/help/matlab/ref/addprop.html to create a custom table property. Custom table properties are not displayed, but they are stored with the table, so you could addprop() a title, and then in the code for tabular disp, check to see if the property exists and if so then display it.
This is all to answer the question of whether it is possible to give a title to a table: the answer is Yes, you can modify the Mathworks-supplied code to allow for a title. If the question where whether there is any supported method, the answer would be what I originally posted: NO.

if you want to display in command widow
fprintf(' your title')
tabulations = table(your parameters)

- Don't forget to add a newline (\n) after the fprintf string,
fprintf('your title\n')
2. The table that is printed by the table() command may be truncated if it is too wide or too tall. This is why it's better to use disp
Compare the following outputs:
T = table(rand(500,1), char(randi(26,500,3)+64))
disp(T)
