Text wrap in Table cell

I made a BIRT report design in which table's cell has dynamic text whose length is more than cell length.

Due to this text is not coming properly and fully.

So please tell me how to wrap the text in new line.

I tried this function wrap , it is working properly i.e wrapping the text to next line if length increases more than 20 ,but it is throwing an exception which is mentioned below. 
 
Plz help. 
 
function wrap(longStr,width){ 
length = longStr.length; 
if(length <= width) 
return longStr; 
return (longStr.substring(0, width) + "\n" + wrap(longStr.substring(width, length), width)); 
} 
 
wrap(dataSetRow["Data Set2::ecp_logon_param_value"],20);

hi mavericks,

I have done this. Pls select the particular cell go to its property editor and go to advanced's property,
and set as shrink to true.

Hi Maverik, 
 
concerning your function you have to add a nullsafety. Looks like the error occurs if the string is null. Change function to: 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>
function wrap(longStr,width){
if(longStr==null) {
return null;
}
length = longStr.length;
if(length <= width)
return longStr;
return (longStr.substring(0, width) + "\n" + wrap(longStr.substring(width, length), width));
}
</pre>

MaverickS

Thanks HPP & cbrell for replying.

HPP - I tried your solution but it is not working.

cbrell - Your solution is working absolutely fine .Thanks a lot.
