You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: im2html.m
    path of file: ./repos/Projects/TaskAssignmentProblem/ImageToHTML
    
    the code of the file until where you have to start completion: function s = im2html(varargin)
%im2html Convert image pixels to HTML table showing pixel colors and values
%   SYNTAX
%
%       im2html(I)
%       im2html(I,[])
%       im2html(I,[LOW HIGH])
%       im2html(BW)
%       im2html(RGB)
%       im2html(X,MAP)
%
%       im2html(___, Name, Value)
%
%       s = im2html(___)
%
%   DESCRIPTION
%
%   im2html produces HTML text con
    
function s = tableAttributes()
%   Return a <table> attributes string. The attributes string sets the
%   <table> class to image-table and sets the cellspacing to "1". The
%   attribute cellspacing is used instead of CSS styles because of uneven
%   browser support.

s = 'class="image-table"';

%==========================================================================
function processOutput(s, num_outputs, options)
%   If the user has asked for an output file, then save the HTML string to
%   a file. Otherwise, if the user did not request an output argument,
%   display the HTML file using the system browser.

if ~isempty(options.OutputFile)
    filename = options.OutputFile;
    fid = fopen(filename, 'w');
    fprintf(fid, '%s', s);
    fclose(fid);
    return;
