來自div的文本溢出

我想將主div的靜態寬度設置爲300px。但是，當任何用戶從Word程序中複製和粘貼文本時，然後從div中更改表格寬度和溢出文本。但我的網站的寬度必須是最大300px。我怎麼解決這個問題？來自div的文本溢出

<html> 
<head> 
<style> 
#main td{ 
max-width:300px; 
} 

#main table{ 
max-width:300px; 
} 

</style> 
</head> 

<body> 
<div id="main"> 
<table width="700" border="1"> 
<tr> 
<td width="800"><p width="900">Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</td>
