# Make a colorful table

For this challenge, you must accept input as a comma-separated list (columns) of a run (rows) of the first letters of any of the colors red, orange, yellow, green, blue, or purple, and output (to stdout) the HTML for a table of those colors.

This is fairly hard to understand, so I'll just give a simple example.

Input:

rgb,gbr,grb


Output (with example screenshot):

<html>
<body>
<table>
<tbody>
<tr>
<td style="background-color: red" width="50" height="50"></td>
<td style="background-color: green" width="50" height="50"></td>
<td style="background-color: blue" width="50" height="50"></td>
</tr>
<tr>
<td style="background-color: green" width="50" height="50"></td>
<td style="background-color: blue" width="50" height="50"></td>
<td style="background-color: red" width="50" height="50"></td>
</tr>
<tr>
<td style="background-color: green" width="50" height="50"></td>
<td style="background-color: red" width="50" height="50"></td>
<td style="background-color: blue" width="50" height="50"></td>
</tr>
</tbody>
</table>
</body>
</html>


Note that the HTML you output need not be valid; it just has to work. By "work", I mean that your output will be pasted into a .html file and viewed in the latest (currently, 9/28/13) Chrome (v 29.0.1547.76). The squares must be 50 pixels width and height. You may have whatever padding between them as you want (Chrome automatically uses 1 pixel of padding, even when you specify padding: 0px, so I can't control that).

Input will always be valid (letters will be one of roygbp), but the rows are not guaranteed to have equal amounts of squares in them. For example, roygbp,ooo is valid and should output

This is , shortest code wins.

I'm afraid that this breaks too many rules, but very creative :D (oh, and btw I count 171 chars) – Doorknob Sep 29 '13 at 2:20 • too bad. In principal, I ought to be able to input the HTML as a string, leaving it in standard output. But I haven't figured out how to do it yet. The byte count seems to be correct. I used the automatic-counter from Wolfram's One-Liner Competition. The spaces are by and large optional. And :> is a single character in Mathematica. – DavidC Sep 29 '13 at 2:25 • lettercount.com says 147 for the current code? Missed to update it ? – C5H8NNaO4 Oct 1 '13 at 10:55 • -> and :> are single characters in Mathematica. And <newline> is included only for readability. – DavidC Oct 1 '13 at 12:09 # JavaScript, 203 146 for(h='<table cellpadding=26>',p=prompt(),i=0;c=p[i++];) h+=","==c?"<tr>":'<td bgcolor=#'+'rF00roFA0oyFF0yg080gb00Fbp808'.split(c)[1]+'>'; alert(h)  Credit to @C5H8NNaO4 for the single loop & cellpadding ideas.

I could shave a few more characters off, but some characters wouldn't paste in correctly. • Nice improvement, especially the colorfinding =) – C5H8NNaO4 Oct 2 '13 at 9:47 • wait did you just copy mine,replaced the color object and moved 2 vars inside the for ? =P +1 anyway – C5H8NNaO4 Oct 2 '13 at 9:55 ## GolfScript, 154144 119 '<table><tr>'\{:^44='<tr>'{"<td bgcolor="['red''orange''yellow''green''blue''purple']{0=^=}?" width=50 height=50>"}if}%  Online test With credit to @bendytree for introducing the no-close-tags trend which allowed me to cut 25 chars. # Python 3 (158) print('<table>',*['<tr>'+''.join('<td width=50 height=50 bgcolor=#%03x>'%dict(r=3840,o=3984,y=4080,g=96,b=15,p=1799)[c]for c in r)for r in input().split(',')])  Cool things: • This uses the * operator to pass multiple arguments to print, saving 6 characters compared to ''.join. • The colors are stored in decimal, then rendered as hex in the HTML. I found this to be much shorter than using string literals directly. # ECMAScript 6: 148 characters alert('<table>'+prompt().replace(/./g,x=>x==','?'<tr>':'<td bgcolor='+'red green orange yellow blue purple'.match(x+'\\w+')+' width=50 height=50>'))  (Just to exercise the fat arrow syntax.) • Could you name your language ECMAScript 6? As the latest firefox is currently the only browser supporting it, it would avoid confusion – C5H8NNaO4 Oct 1 '13 at 13:43 • Ok. And thanks for the information. (Sadly I had no time to test in other browsers. But one thing is sure: in Firefox is available since version 22, not only the latest. ;)) – manatwork Oct 1 '13 at 13:53 • =) Thanks, ( I would love seeing chrome supporting ES6 soon). Well yeah :P "latest" is the wrong word here, I'm not using firefox and am not up to date with their versions. So i think "the newer firefox browsers" would have been more appropriate.

Update 1; if you silence (or just ignore) E_NOTICE you can remove the quotes around strings that start with letters, shaving off another 18 characters

Update 2; trimmed 1 character!

<?php echo'<table cellpadding=50><tr>';$a=[r=>f00,g=>'080',b=>blue,o=>fa0,p=>'808',y=>ff0];foreach(str_split($x)as$b){echo$b==','?'<tr>':"<td bgcolor=#$a[$b]>";}?>

• You could change b=>'00f' to b=>blue to save 1 character, and remove cellpadding=50 to save 15. – Doorknob Oct 3 '13 at 23:41
• @Doorknob Nice catch, but removing the cellpadding would make the boxes 2px x 2px; wouldn't that be cheating out of the assignment specification? – TheBigB Oct 4 '13 at 17:13

• That can be reduced to 187 with some simple tricks: \$><<'<table>'+gets.chop.split(?,).map{|r|'<tr>'+r.chars.map{|t|"<td bgcolor=#{'red green orange yellow blue purple'.match(t+'\w+')[0]} width=50 height=50></td>"}*''+'</tr>'}*''+'</table>'. – manatwork Oct 1 '13 at 10:24
