The column which has the description field in the Pageblocktable is showing multiple lines, increasing the height of a row. I want to restrict ONLY one line (default height) per row in the table.

I'm able to do this using OVERFLOW:HIDDEN property in CSS but it is pulling the whole data. I wanted to try the JavaScript substring method in this. I've used JavaScript substring method in a vf page to show ONLY the allowed number of characters in a output text.

I would like to know how to use the JavaScript substring method for a column(Description) in a Pageblocktable to pull only limited number of characters for all values when the page loads and show ONLY one line for a row with default height.

    can you post how you pull the data, are you using controller or javascript remoting purely to populate the data in the table?

If you are just wanting to truncate the data once the page has loaded you can add a CSS class to the column in the Visualforce:

<apex:column styleClass="truncate" ... />

and truncate the text by using that class in a jQuery selector like this:

<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<script>
var j$ = jQuery.noConflict();
j$(document).ready(function() {
    j$('td.truncate').each(function() {
        var td = j$(this);
        td.text(td.text().substring(0, 50));
    });
});
</script>
</apex:page>
