MATLAB: Can the ui table also act as the plot legend

plotyy legend ui table gui

I have a GUI with a uitable as well as a plot. Instead of creating a legend, I want to have the line color and marker for the data points to be added in a column to my ui table. Can this be done? This would save space on my GUI, as well as make it easier for displaying data.

yes you absolutely can. It just takes some basic knowledge of HTML and knowing how to get/parse/extract handle properties.
This link http://www.mathworks.com/matlabcentral/answers/92437-how-do-i-change-the-color-of-individual-cells-in-uitable-in-matlab-7-10-r2010a is a good starting point but i added additional information into getting the different parameters in the case that you didn't store them before hand. I'd use the debugger and step through my example to see how to fit your linestyle+marker+color data.
function multi_colored_uitable
%generate random data for example
sampdata = randi(100,10,4);
%get sample plot with sampdata with varying colors and markers for lines
    markers = ' -.o';
    colors = 'bgrm';
    hfig = figure;hax = axes('position',[.1 .55 .8 .4]); hold on
    for ind= 1:4
        hplot(ind) = plot(sampdata(:,ind),['-' markers(ind) colors(ind)]);
    end
% Create a cell array with HTML code for line data
    for ind = 1:4
        %scale colors to 255 to be converted to hex
        linecolor = 255*get(hplot(ind),'Color'); 
        colorinhex = dec2hex(linecolor,2)';
        marker = get(hplot(ind),'marker');
        if strcmp(marker,'none')
            marker=[];
        end
        linestyle = get(hplot(ind),'Linestyle');               
        linedata{1,ind} = colText([linestyle marker],['#' colorinhex(:)']);  
    end
      tabledata = [linedata;mat2cell(sampdata,ones(1,10),ones(4,1))];
% Define the column names
colnames = {'first', 'second', 'third', 'fourth'};
uitable(hfig, 'Data', tabledata, ...
      'ColumnName', colnames, ...
      'Units', 'normalized', ...
      'Position', [.1 .05 .8 .4]);
end
function outHtml = colText(inText, inColor)
% return a HTML string with colored font
outHtml = ['<html><font color="',...
      inColor, ...
      '">', ...
      inText, ...
      '</font></html>'];
end
