[jira] Commented: (DISPL-151) Column grouping and 2 row headers

JIRA jira@codehaus.org
    [ http://jira.codehaus.org/browse/DISPL-151?page=comments#action_42672 ]

Jeff Sheets commented on DISPL-151:
-----------------------------------

I also voted on this issue, and would love to see it completed soon.  Until this feature is added I am added a grouping master header row by using this javascript at the end of the page:

/* This javscript block adds a master header row to the table */

    function appendHeaderCell(theadRow, colSpan, className, text) {
      var headCell = theadRow.insertCell(theadRow.cells.length);
      headCell.colSpan = colSpan;
      headCell.className = className;
      headCell.innerHTML = text;
    }
   
    var masterRow = document.getElementById("myDisplayTagTableId").tHead.insertRow(0);
    appendHeaderCell(masterRow, 1, "", "");  //First column doesn't have a grouped header
    appendHeaderCell(masterRow, 3, "reportheader master-reportheader", "NAME");  //The next three columns are grouped
    appendHeaderCell(masterRow, 2, "", "");  //These two are not grouped
    appendHeaderCell(masterRow, 4, "reportheader master-reportheader", "TEST GROUP");  //The next 4 columns are grouped

> It would be nice to be able to group columns together so that the table header has 2 rows to show groupings. For example, I want to display a list of people with info about the person. I would like to have a header like:
> |           |        NAME           |       |            |
> |           |-----------------------|       |            |
> | PERSON_ID | LAST | FIRST | MIDDLE | PHONE | DEPARTMENT |...
> ----------------------------------------------------------
> Data...
> I envision something like...
> <display:table id="searchResults" name="..." >
>   <display:column property="id" title="PERSON_ID"/>
>   <display:column title="NAME">
>     <display:column property="lastName" title="LAST"/>
>     <display:column property="firstName" title="FIRST"/>
>     <display:column property="middleName" title="MIDDLE"/>
>   </display:column>
>   <display:column property="phone" title="PHONE"/>
>   <display:column property="dept" title="DEPARTMENT"/>
> </display:table>
> or
> <display:table id="searchResults" name="..." >
>   <display:column property="id" title="PERSON_ID"/>
>   <display:column property="lastName" title="LAST" GROUP="NAME/>
>   <display:column property="firstName" title="FIRST" GROUP="NAME/>
>   <display:column property="middleName" title="MIDDLE" GROUP="NAME/>
>   <display:column property="phone" title="PHONE"/>
>   <display:column property="dept" title="DEPARTMENT"/>
> </display:table>
> ... where "GROUP" is a new attribute.
> I would also expect that it would still be able to preserve sorting on the grouped columns. For example, I would still be able to sort on first, last, and middle names.
