Create a CSP Page with DataTable

Hello -

There are multiple means of rendering a table in a "grid", from a simple html table populated with an SQL query, to ZEN "Grid" object

For the html table, the following code would give you a table from the SQL query

<script language=SQL name="query">
SELECT * FROM User.DataTable
</script>
<table border=1 bgcolor="">
 <tr>
 <csp:while counter=queryCol condition="(queryCol<query.GetColumnCount())">
  <th align=left><b>#(query.GetColumnHeader(queryCol))#</b></th>
 </csp:while>
 </tr>

 <csp:while counter=queryRow condition=query.Next()>
 <tr class='#($S(queryRow#2:"DarkRow",1:"LightRow"))#'>
  <csp:while counter=queryCol condition="(queryCol<query.GetColumnCount())">
   <td>#(query.GetData(queryCol))#</td>
  </csp:while>
 </tr>
 </csp:while>
</table>
 

For the ZEN example, take a look at your "local" sample page:  <localhost>/csp/samples/ZENTest.DynaGridTest.cls

Consider using REST. Creating REST in InterSystems Cache 2017.2 is very easy.

you may take this example from OpenExchange:
 https://openexchange.intersystems.com/package/Light-weight-EXCEL-download

Al you have to do is to out-comment in  ClassMethod OnPreHTTP()  
this line :  #; set %response.ContentType="application/vnd.ms-excel"

and the table goes to your browser.
