Controlling repeated table header

Hi,

I'm new to BIRT and I'm using standard BIRT report viewer deployed on a tomcat server. When I export the reports, I get different results regarding to the table header:

1. HTML view: repeated every page (40 rows)
2. XLS: not repeated
3. ODS: repeated every 40 rows

I want to enable repeated table header in the html view, and not in XLS and ODS exported report. I tried to add script to reports' beforeRender method to check output type and set the repeatHeader property accordingly but it's not working. I read the BIRT's table element reference and I found that repeatHeader property is not runtime settable.

What is the correct way to do this?

You can use repeateHeader in your tables onCreate() like this 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>if(reportContext.getOutputFormat() != "pdf") {
this.repeatHeader = false;
}</pre>
 
Or if you are wanting to set it in onPrepate() you can use 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>this.setRepeatHeader(false);</pre>

Hi, kclark! Thank you for your response. I tried both methods, but the results are still the same. Here's my code on the table's onCreate method: 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>
rh = false;
format = reportContext.getOutputFormat().toLowerCase();

if (format.equals("pdf") || format.equals("html")) {
rh = true;
}

this.setRepeatHeader(rh);
</pre>
 
I'm using birt report viewer example webapp supplied in the birt runtime package. When the report displayed in the webapp, the table header is repeated on each page. And when I export the report to ODS with the button on the toolbar, the table header is still repeated every 40 rows (as set in page break interval). 
 
I suspect the onCreate script was not executed when the report exported to ODS (or any format). When i set rh to false in the if block, the table head in both reports displayed in the webapp and exported ODS is not repeated. 
 
Thanks,
