From R2018a, we can display table array data in uitable.
The following is an example of reading data from PostgreSQL and show it in uitable.
%% Access to database
conn = database('db_name','usename', 'password', ...
'Vendor','PostgreSQL', ...
'Server','localhost','PortNumber',5432);
tableName = 'table_name';
% Read data from SQL
data = sqlread(conn, tableName);
%% plot in uitable
f = uifigure;
uit = uitable(f, 'Data', data);

After displaying the Table, I want the user to be able to select lines from this table,
I want than later to do something with the selected lines

uitable has a property CellSelectionCallback, and by using this, selected lines can be caught up.
Here is an example of do something from selected lines (app.data and app.selected are properties added in AppDesigner)
app.UITable.CellSelectionCallback = {@selectedChange, app};
function selectedChange(src, eve, app)
% Get selected lines
app.selected = eve.Indices(:, 1);
% Extract only selected lines from original data
selectedData = app.data(app.selected, :);
% Do something on selected lines
% for example,
% m = mean(selectedData);
end
