increase or decrease "RowNames" column - table

How do I increase or decrease "RowNames" column?

Similar to the command:

'ColumnWidth', {100,100,100}

LastName = {'Smith';'Johnson';'Williams';'Jones';'Brown'};
Age = [38;43;38;40;49];
Height = [71;69;64;67;64];
Weight = [176;163;131;133;119];
T = table(Age,Height,Weight,'RowNames',LastName)
x = 0:pi/100:2*pi;
y = sin(x);
hAx=subplot(2,1,1);                                                          
hUI=uitable('Data',T{:,:},'ColumnName',T.Properties.VariableNames,...           
'RowName',T.Properties.RowNames,'Units', 'Normalized', 'Position',hAx.Position , 'ColumnWidth' , {100,100,100});
delete(hAx)                     
hAx=subplot(2,1,2);             
plot(x,y)

To set row-name column width to auto-fit the row-label-width:

If your goal is to fit the row name column to the width of the labels, create the uitable within a uifigure. The row-name column is auto-fitted in uifigures but not in regular figures. Also, use tiledlayout instead of subplot -or- turn off the AutoResizeChildren property of the uifigure to avoid an error produced by subplot.

Also note the use of axis and figure handles.

% Set up data
LastName = {'Smith';'Johnson';'Williams';'Jones';'Brown'};
Age = [38;43;38;40;49];
Height = [71;69;64;67;64];
Weight = [176;163;131;133;119];
T = table(Age,Height,Weight,'RowNames',LastName);
x = 0:pi/100:2*pi;
y = sin(x);

% Plot uitable
fig = uifigure();
tlo = tiledlayout(fig,2,1); 
hAx(1) = nexttile(tlo);
hUI = uitable(fig,'Data',T{:,:},'ColumnName',T.Properties.VariableNames,...
    'RowName',T.Properties.RowNames,'Units', 'Normalized', 'Position',hAx(1).Position ,...
    'ColumnWidth' , {100,100,100});
hAx(2)=nexttile(tlo);
plot(hAx(2),x,y)     

delete(hAx(1)) % delete *after* 2nd axes are created

Also note the use of axis and figure handles.

% Create figure, turn off AutoResizeChildren
fig = uifigure('AutoResizeChildren','off');
hAx(1) = subplot(2,1,1,'Parent',fig);                                                          
hUI=uitable(fig,'Data',T{:,:},'ColumnName',T.Properties.VariableNames,...           
    'RowName',T.Properties.RowNames,'Units', 'Normalized', 'Position',hAx.Position , ...
    'ColumnWidth' , {100,100,100});
hAx(2) = subplot(2,1,2,'Parent',fig);
plot(hAx(2),x,y)     

delete(hAx(1)) % delete *after* 2nd axes are created    

To control width of row-name column:

I am not aware of a method that directly sets the column width of the row name. A workaround is to move the row names into column 1 of the data itself and then format that colum to make it look similar to the row-name column using uistyle & addStyle (requires Matlab >=r2019b). This requires you to use uifigure. Remember to index the table data by offsetting the column numbers by 1 to account for the row names.

The upper table is the default table with a row-name column. The lower table is without a row-name column but with formats column 1 to make it look like a row-name column.

fig = uifigure();
tlo = tiledlayout(fig,2,1); 
hAx(1)=nexttile(tlo);
hUI=uitable(fig,'Data',T{:,:},'ColumnName',T.Properties.VariableNames,...
    'RowName',T.Properties.RowNames,'Units', 'Normalized', 'Position',hAx(1).Position , 'ColumnWidth' , {100,100,100});

hAx(2)=nexttile(tlo);
C = [T.Properties.RowNames, table2cell(T)];
hUI2=uitable(fig,'Data',C,'ColumnName',[{''},T.Properties.VariableNames],...
    'RowName',[],'Units', 'Normalized', 'Position',hAx(2).Position , 'ColumnWidth' , {65,100,100,100});
colStyle = uistyle('BackgroundColor',hUI2.BackgroundColor(2,:),'FontWeight','bold'); 
addStyle(hUI2,colStyle,'column',1)

delete(hAx)

And I thought it would be just one line of code

Most of the code in my answer is setting up the table. Depending which option you choose, there are really only about 1-4 lines of code that you need to implement.
