To use this Javascript for your own, copy the contents of the textbox below, and paste them into Notepad. Then, save the contents as a .htm or .html file. The Javascript is now yours! Just ensure you give me proper credit for creating it.

<form name="tableCreateForm" onsubmit="printTableCode(this); return false;" action="">
Number of Rows: <input type="text" name="numRows" value="4" /><br />
Number of Columns: <input type="text" name="numColumns" value="5" /><br />
Table Width: <input type="text" name="tableWidth" value="600" /><br />
Table Background Color (in hexadecimal): #<input type="text" name="backgroundColor" value="ffffff" /><br />
Border Size (in pixels): <input type="text" name="borderSize" value="1" /><br />

Click once in the text box to highlight the HTML code. Then, press Ctrl + C (Apple + C for Mac users) to copy the table code to the clipboard, and then Ctrl + V (Apple + V for Mac users) to paste the table code into your favorite HTML code editor. Now you have your HTML table!
