I believe you can do this with a TableDecorator. If you override the startRow() method and use a class variable you can check if this is the first row in the table:
public MyDecorator extends TableDecorator {
boolean doneFirst = false;
public String startRow() {
if (!doneFirst) {
doneFirst = true;
return "<tr>[type the rest of your inserted row here]</tr>";
}
}
}

You can add any text or html tags to the <td> cells by placing it inside the <display:column> tag's body:
<display:table name="result">
<display:column title="Last Name">
<input type="checkbox" value="${result.rowId}" />${result.lastName}
</display:column>
</display:table>
or you could use:
<display:column property="lastName" title="Last Name" />
and then in the TableDecorator write:
public String getLastName() {
MyBean row = (MyBean)this.getCurrentRowObject();
return "<input type=\"checkbox\" value=\"" + row.getRowId() +"\" />" + row.getLastName();
}
Is this the sort of thing you were looking for?
Mr. Raible also has this demo for editable tables:
