      That was a Sage cell just now,
      which has nothing to do with tables.
      But we needed someplace to test placement right after a division heading.
      Carry on.

    <p>
      A very minimal table, hence with left-justified cells,
      no borders.
      We do wrap the tabular element in a table element to get centering,
      numbering and a caption.
      Footnotes inside cells are tested here.

      Note that tables may be constructed using the
      <url href="http://www.latex-tables.com/" visual="www.latex-tables.com"><latex /> Complex Table Editor</url>
      tool online at <c>latex-tables.com</c> and then exported in <pretext /> syntax.

      Tables can be used and abused many ways.
      We describe long division of polynomials by using vertical and horizontal borders on individual entries of a <tag>tabular</tag>.
      The division lines are slightly thicker than the subtraction lines.
      This is a good example of the typical abuse of tables for horizontal and vertical layout.
      At least we have called it a
      <q>Figure,</q>
      not a
      <q>Table</q>.

        This example tests several things.
        In <latex /> output, figures,
        tables, listings and side-by-sides are
        <q>floats</q>
        whose placement can migrate, but we have tries to supress this behavior.
        However, a float that is the first item of an
        <q>environment</q>
        (like a theorem or an example) can still float to a position
        <em>before</em> its title.
        If that does not happen here,
        then our additional defenses are working.
      </p>
      <p>
        This example also checks that the total number of columns is correctly computed from the first row,
        which features several <c>colspan</c> attributes.
      </p>
    </example>
    <p>
      A bare minimum table
      (one row with one cell)
      to test edge cases:
    </p>
    <table xml:id="table-minimal">
      <title>One entry table</title>
      <tabular top="medium">
        <row bottom="medium" left="minor">
          <cell right="minor">One</cell>
        </row>
      </tabular>
    </table>
    <p>
      Table cells with a fixed width where text wraps are known as
      <q>paragraph cells</q>. A cell will be created as a paragraph cell if and only if it has <tag>p</tag> children.
      And such cells should <em>only</em>
      have <tag>p</tag> children.
      The width of a paragraph cell is determined by a <c>width</c> attribute on the corresponding <tag>col</tag>
      (as a percentage).
      If the column has a non-paragraph cell with contents that are wider than the paragraph cells,
      results will be undesirable.
      There is presently no implementation for a paragraph cell that has a <c>colspan</c> greater than <m>1</m>,
      although cells with <c>colspan</c> greater than <m>1</m> that are above or below a paragraph cell will behave.
      Setting <c>width</c> on a <tag>col</tag> that has no paragraph cells may produce unexpected results.
      A <c>valign</c> for the parent <tag>row</tag>
      (or the ambient <tag>tabular</tag>)
      can control vertical alignment
      (top, middle, or bottom).
      A paragraph cell's <c>halign</c> attribute (left, center,
      right, or justify) controls how the text is justfied.
      Cells inherit <c>halign</c> from <tag>row</tag>,
      <tag>col</tag>,
      and <tag>tabular</tag> in that order of preference.
      In a non-paragraph cell where <c>halign='justify'</c>,
      the horizontal alignment will match the behavior of <c>halign='left'</c>.

      Table cells can have multiline content using <tag>line</tag> elements.
      This is not the same thing as a paragraph cell<mdash />line breaking will happen precisely where the author tells it to.
      A <tag>line</tag> will not break, even on a narrow screen.
      If a cell uses a <tag>line</tag>,
      it must only use a sequence of <tag>line</tag>s and no other content.
      As with paragraph cells,
      you can use a <c>valign</c> attribute for the row.

      Tables are formed in <latex /> output with copious use of the <c>\multicolumn</c> macro to override more global alignment settings,
      and to spread the content of one cell across several columns.
      However, sometimes <latex />'s special characters have behaved badly in this situation.
      So the table below, two items per row,
      is just designed for <latex /> testing.
      But of course, it should still render fine in other formats.
      The three test cases are from <xref ref="section-urls" type="text-global" />,
      but without 50 alphabetic characters and 8 digits,
      which should not be problems in this context.
      In order to test the use of a percent sign (<c>%</c>) in a URL, we follow it by two hex digits,
      specifically,
      <c>58</c>,
      which is a way to represent the character <c>X</c> in a <init>URL</init>.
      The first column's entries are <em>forced</em>
      to be wrapped in a <c>\multicolumn</c> by specifying their horizontal alignment.
      The second column's entries <em>will not</em>
      be wrapped in a <c>\multicolumn</c>.
      So the two columns will look identical,
      other than the first having a left alignment,
      and the second has the default center alignment.
      (This table is known to render poorly in a Jupyter notebook.
      The cause is four dollar signs present in rows 1 and 3, and is explained in <xref ref="subsection-jupyter-dollars" text="type-global" />.)

      We now finish this section with some <em>long</em> tables.
      Ones that will not fit on a single printed page.
      So this is only of interest when producing this sample article as a <init>PDF</init>.
      First a
      <q>naked</q>
      tabular, which should force a new page to start,
      and then still overrun the end of the page.

    <p>
      When you wish to allow a <tag>tabular</tag> to split itself at a page break,
      you can add the attribute <attr>break</attr> with the value <c>yes</c>.
      Certainly this will control a <tag>table</tag> or <tag>tabular</tag> which is longer than a page,
      but will also allow a shorter one to break.
      This might useful in a draft stage before undertaking page-fitting.

      Here is the long <tag>tabular</tag> again,
      but with the <attr>break</attr> attribute set to <c>yes</c>.

    <p>
      This device is not ideal,
      as some features of tables are not behaving as expected.
      More precisely,
      we switch from the standard <latex /> <c>tabular</c> environment to the <c>longtable</c> environment from the package of the same name when table-breaking is requested.
      So there may be some undesirable interaction with other packages.
      For one, full-width horizontal rules seem to become as wide as the page
      (rather than as wide as the tabular).
      The following table is <xref ref="horizontal-rules-table" text="type-global" /> repeated but as a breakable <tag>tabular</tag>.
      The <c>longtable</c> package documentation suggests it accomodates the <c>array</c> package,
      but it also seems to make a variety of redefinitions.
      Furthermore,
      a panel of a side-by-side cannot be a breakable tabular,
      or a <latex /> compilation error occurs.

    <p>
      The <c>longtable</c> package allows for headers and footers indicating continued tables.
      A possible enhancement is to support this feature in the case of a long table.
