Having trouble writing multi-line text into table cell

Question

I am using Java Wicket to create a table. I want to write a cell made of multiple lines; each line within the cell represents a data item.

List<EntityClassModel> classesList = classService.getClassesByNotificationId(nitem.getModelObject().getId());
nitem.add(new Label("classnamelab", getClassNames(classesList)));

However, when I concatenate the lines, inside getClassNames , using classNames.append("<br>"); the page displays Latin 101<br>Latin 103 . From Chrome I Save As the page and opened it in Notepad++. It showed <td class="laclasses">Latin 101&lt;br&gt;Latin 103</td> .

I also tried the code classNames.append("<br>"); . It was displayed in the cell as Latin 101<br>Latin 103 , wich is worse.

Using the saved files, I copied a row and changed the text to <td class="laclasses">Angle 101<br>Bracket 103</td> . That showed the data Angle 101 and Bracket 103 on two lines within the cell, which is what I want. Developer Tools showed the coding on five lines.

<td class="laclasses">
   "Angle 101"
   <br>
   "Bracket 103"
</td>

The style sheet includes the block

td.laclasses
{
    width: 140px;
    padding-right: 1em;
    text-align: left;
    white-space: pre;
}

Is there a simple way for Wicket to encode the multiple string so that they show as multiple lines within a cell?

Answer 1

您应该使用org.apache.wicket.markup.html.basic.MultiLineLabel 。

Answer 2

The MultiLineLabel worked. I had to change the style as the data was inside a <p>...</p> .
