Few questions

1)Would the table always be the same size (same number of letters)
2)What is the intend of the process (is for a game of some sort)?
3)When you say one letter at a time do you mean the user will have to click the button everytime to get a new letter or do you mean starting to show the letters one at a time with a slight delay in between?
4)From where are the letters coming, are the words kept in a database?
5)Are you using a server side language like php or is it Javascript etc.?

1) The table and boxes' size will not change.

2) The interactivity will take place  in an essay I wrote:

http://www.pinyinology.com/wheel/fortune.html

The Chinese letters will appear one after another, then disappear altogether  by pushing the 'reset' button.  My intention is that an expert does a piece of the work, i then apply  the code to  that page.

3) Clicking the button one time will cause  the letters to appear one by one continuously. Not one clicking one letter. The letters can appear one by one, with or without stop between the letters.

4) I prefer no database at all.  Everything  is done on the html page, with javascript scripting.

5) I like the letters' display and hide are all manipulated by scripting only.

6). If it is hard to achieve the appearance of one letter after another, all the letters can show up altogether in the mean time.

<input type='button' value='reset' name='name2' onClick="hideIt()" />
 
</form>
 
<br />
 
<p>
When the page is opened, the top table, not the bottom one, appears. When clicking the 'show letters' button, the letters will apear in the boxes of the TOP table. It is better that the letters appear one after another from left to right, rather than in the same time.    </p>
 
<p>
When clicking the 'reset' button, all letters disappear. 
</p>
 
<p>
Note:  there is only one table, not two.
