# Continuation head and continuation note

## Task

On a multi-page article list the readers should see that the table continues and where it ends: the first page carries the normal head, the following pages a head with the addition “Continued”. At the end of every page except the last one there is a note “continued on next page”; only the last page shows the closing foot.

## Decision

The recipe Simple table with automatic breaking is enough as long as head and foot may look the same on all pages. If they should differ per page, the automatic mechanism still stays in place: `<Tablehead>` and `<Tablefoot>` can be declared several times, and the attribute `page` determines which variant appears on which page. The Publisher picks the right one at each break by itself.

One limit is worth knowing before you start: the contents of head and foot are evaluated when the table is built, not at each page break. A real page number (“continued on page 17”) can therefore not be output here; see Limits.

## Solution

The data is the unchanged Confixa article list from the first recipe.

### Step 1: two table heads

The head for the first page gets `page="first"`, the one for the following pages `page="all"`. As soon as a `first` variant is declared, `all` applies to all pages except the first; the order of declaration does not matter.

    <Tablehead page="first">
      <Tr background-color="lightgray">
        <Td><Paragraph><B><Value>Item no.</Value></B></Paragraph></Td>
        <!-- the other column heads as before -->
      </Tr>
    </Tablehead>
    <Tablehead page="all">
      <Tr>
        <Td colspan="5"><Paragraph><I><Value>Continued</Value></I></Paragraph></Td>
      </Tr>
      <Tr background-color="lightgray">
        <Td><Paragraph><B><Value>Item no.</Value></B></Paragraph></Td>
        <!-- the other column heads as before -->
      </Tr>
    </Tablehead>

The continuation head may have more than one row: here an additional row with the italic “Continued” sits above the column heads.

### Step 2: two table feet

For the feet the counterpart of `first` is, fittingly, `last`: if a `last` variant is declared, the `all` variant appears on all pages except the last one. This puts the note “continued on next page” exactly on the pages where the table goes on:

    <Tablefoot page="all">
      <Tablerule rulewidth="0.5pt"/>
      <Tr>
        <Td colspan="5" align="right">
          <Paragraph><I><Value>continued on next page</Value></I></Paragraph>
        </Td>
      </Tr>
    </Tablefoot>
    <Tablefoot page="last">
      <Tablerule rulewidth="0.5pt"/>
      <Tr>
        <Td colspan="5" align="right">
          <Paragraph><Value>Net prices per PU</Value></Paragraph>
        </Td>
      </Tr>
    </Tablefoot>

If the last page should not show any foot at all, simply declare the variant empty: `<Tablefoot page="last"/>`.

### Complete example

The runnable project is also available in the examples repository; the data file is the same as in the first recipe. The A5 format and the generous `padding` only serve to produce three pages for the illustration.

    </Layout>

## Limits

- No real page numbers in the note. The contents of `<Tablehead>` and `<Tablefoot>` are evaluated once when the table is built, not at every page break; `sd:current-page()` therefore returns the same number in every foot. If you need “continued on page 17”, you have to portion the table yourself and set the feet per portion; this is shown in the recipe Breaking complex tables manually.
- Dynamic content in head or foot (such as subtotals or a running sum) is possible with the mechanism of the `data` attribute on `<Tr>` plus the variable `$_last_tr_data`, see Headers and footers with running sum.
- Repeating section headings: If the current group heading should reappear after the break, mark its row with `sethead="yes"`, see Headers and footers (dynamic).
- Reference: `<Tablehead>` and `<Tablefoot>`.
