A `<tc:sheet/>` tag can contain any number of `<tc:column/>` tags. The `<tc:column/>` tag is a container, which may contain outputfields, labels, progress bars or even tab groups.

Two attributes should be recognized in a sheet. The data of the sheet is set in the `value` attribute. The variablename of a single entry is set by the `var` attribute, which can be used in the `<tc:column/>` tags. In this example, also the `rows` attribute is set. So only four rows are shown at a time.

In most cases, you should set `labelLayout="skip"` for components which have usually a label. Otherwise those components have a negative affect on the proportion of the sheet.
For components with a label the attribute `margin-bottom` is set. The margin is add to the height of a row.

    <tc:sheet value="\#{sheetController.solarList}"
        var="solarobject" rows="4">
      <tc:column label="Name">
        <tc:out value="\#{solarobject.name}" labelLayout="skip"/>
