MATLAB: Setting UI table size to start from the top row and have a scroll bar

autosizingfigureuitable

Hello I am trying to plot data in a table but when I set it to size automatically, I lose my scroll bar and hence the ability to see data on top of the figure. The only way for me to do that is to increase my window size, which in this case is unreasonable. I want the output of this function to be a figure where the first row of the table is at the top and there is a scroll wheel on the right hand side.

clear;
figfig = figure('Name','Final Results','NumberTitle','off');clf;
X = rand(150,9);
XCell = cellstr(string(X));
A(1:150,1:9) = string("#FFFFFF");
A = cellstr(A);
outHtml = strcat('<html><table border=0 width=400 bgcolor=', ...
 A, ... % Choose the appropriate color for each cell
 '"><TR><TD>', ...
 XCell, ... % Convert num data to cell of chars
 '</TD></TR></body></html>');
u = uitable(figfig,'Data',outHtml);
table_extent = get(u,'Extent');
figure_size = get(figfig,'outerposition');
desired_fig_size = [figure_size(1) figure_size(2) table_extent(3)+15 table_extent(4)+65];
set(u,'outerposition',[1 1 table_extent(3) table_extent(4)])
set(figfig,'outerposition', desired_fig_size);
end

Best Answer

Not sure why you're using HTML here...

u = uitable(figfig,'Data',outHtml,'Units','normalized','OuterPosition',[0,0,1,1]);

Then remove the other lines dealing with the uitable size/position.

MATLAB: Add a cell array in double for one more column in uitable

Convert the numeric array into a cell array before concatenating. Then use the cell array as the input to the uitable command.

%% Start
clear all; close all; clc;
rnames = {'<html><font size=+1>First','<html><font size=+1>Second','<html><font size=+1>Third','<html><font size=+1>fourth','<html><font size=+1>fifth'};    % These are your row names
cnames = {'<html><font size=+1>X=data','<html><font size=+1>Y-Data','<html><font size=+1>[Z-Data]','<html><font size=+1>[unit-Data]'}; % for bold <h1>World</h1>
x = [38;43;38;40;49];
y = [71;69;64;67;64];
z = [176;163;131;133;119];
Units = {'mm/N';'1/N';'1/Nmm';'1/Nmm^2';'1/Nmm^3';};
join_all=[num2cell([x y z]), Units];
fig = figure('Position', get(0, 'Screensize'),'Name','Numbers');
t = uitable(fig,'Data',join_all,'ColumnName',cnames,...
    'RowName',rnames,'Position',[20 20 1050 800] ,'FontSize',20); %,'Units','Normalized','Position',[0 0 1 1],'fontSize',19
set(t,'ColumnWidth',{100})
table_extent = get(t,'Extent');
set(t,'Position',[1 1 table_extent(3) table_extent(4)])
figure_size = get(fig,'outerposition');
desired_fig_size = [figure_size(1) figure_size(2) table_extent(3)+15 table_extent(4)+65];
set(fig,'outerposition', desired_fig_size);

I also fixed the fact that you wrote join-all instead of join_all in the uitable command.

MATLAB: How to get the cells in a table created in GUIDE to fill the full size of the table

There are two possible approaches to achieve this result:

Approach 1 - Change the table's column widths so they match the width of the table. You can do this manually in GUIDE by right-clicking on the table, selecting Property Inspector, and modifying the ColumnWidth property. Or you can do this programmatically in the OpeningFcn function, as shown:

% Change the tables column widths to match the width of the table

table = handles.uitable1;

table.Units = 'pixels';

width = table.Position(3)-31; % subtracting by 31 to account for row header

ncol = size(table.Data, 2);

table.ColumnWidth = num2cell(ones(1,ncol)*width/ncol);

Approach 2 - Change the table's width and height so they match the width and height of the collection of cells in the table. You can do this programmatically in the OpeningFcn function, as shown:

% Change the tables width and height to match the width and height of cells in the table

table = handles.uitable1;

table.Position(3) = table.Extent(3);

table.Position(4) = table.Extent(4);
