Overview

The tabular views make heavy use of Angular directives, to keep the source code concise. However, it can be tricky to understand what all those non-standard-HTML attributes are for. This page sheds some light on the mystery. In addition, further configuration options / variants are described.

Notes on Directives

Refresh Button

ng-class="{active: autoRefresh}"

icon icon-id="refresh" icon-size="36"

tooltip tt-msg="autoRefreshTip"

ng-click="toggleRefresh()"

Notes on Main Table

onos-table-resize

Note that the table view makes use of two HTML <table> elements; the first for the (non-scrolling) table headers, and the second for the (scrolling) table contents:

Table Header

onos-sortable-header

sortable

sort-callback

sort-callback="sortCallback(requestParams)"

Table Column Options

The first thing to note about the table columns is that the column headers use td tags (not th tags).

Columns may be labeled, or have no label at all (e.g. for columns with icons). The following table lists the possible options to be applied to a column:

Name	Usage	Description	Required for
`col-width`	attribute col-width with pixel value	Sets column to that specific width in pixels	`onos-table-resize`
`table-icon`	class	Sets column width to a good size for icons	`onos-table-resize`
`colId`	attribute colId with value	Used to identify columns for sorting in ascending or descending order	`onos-sortable-header`
`sortable`	attribute without value	Allows that column to be sortable	`onos-sortable-header`

See the following code snippet for an example:

<div class="table-header"
     onos-sortable-header sort-callback="sortCallback(requestParams)">
     <table>
         <tr>
             <td colId="active" class="table-icon" sortable></td>
             <td colId="id" sortable>Foo ID </td>
             <td colId="bar" sortable>Bar </td>
             <td colId="baz" sortable>Baz </td>
             <td colId="desc" col-width="475px">Description </td>
         </tr>
     </table>
</div>

Table Body

A typical table body might look something like this:

<div class="table-body">
    <table>
        <tr ng-if="!tableData.length" class="no-data">
            <td colspan="5">
                No Foos found :(
            </td>
        </tr>
 
        <tr ng-repeat="foo in tableData track by $index"
            ng-click="selectCallback($event, foo)"
            ng-class="{selected: foo === sel}">
            <td class="table-icon">
                <div icon icon-id="{{foo._iconid_active}}"></div>
            </td>
            <td>{{foo.id}}</td>
            <td>{{foo.bar}}</td>
            <td>{{foo.baz}}</td>
            <td>{{foo.desc}}</td>
        </tr>
    </table>
</div>

The first <tr> element is made visible only if there are no rows of table data.

The second <tr> element is a pattern that is used repeatedly by Angular to create a row for every element in the tableData variable (defined on our controller scope). Note the icon column <td> is classed with "table-icon" so that it is sized correctly.

Table Row Options

If you wish to create a table where one item spans multiple rows, you can specify your data <tr> elements to look something like this:

<tr ng-repeat-start="foo in tableData track by $index">
    <td>{{foo.id}}</td>
    <td>{{foo.bar}}</td>
    <td>{{foo.baz}}</td>
    <td>{{foo.zoo}}</td>
</tr>
<tr>
    <td class="desc" colspan="4">{{foo.desc}}</td>
</tr>
<tr ng-repeat-end>
    <td class="instructions" colspan="4">{{foo.instructions}}</td>
</tr>

Note the use of the ng-repeat-start directive in the first row, and the ng-repeat-end directive in the last.

With appropriate styling, the rows can be made to look as if they belong together. The Intent View makes use of this technique. (See intent.html and intent.css for more details)
