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
> Column grouping and 2 row headers

> 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.
