Preamble

This shows how to use the LayoutTable function in niceTables.pl. Note that the niceTables.pl macro is automatically loaded by PGML.pl, so it is not necessary to load it explicitly.

The PGtikz.pl macro is also used in this example to demonstrate inserting a dynamically generated image into a table.

$a   = random(0, 3);
$ans = Compute("x^2 + $a")->reduce;

$graph = createTikZImage();
$graph->tikzLibraries('arrows.meta');
$graph->BEGIN_TIKZ
\tikzset{>={Stealth[scale = 1.5]}}
\filldraw[
    draw = LightBlue,
    fill = white,
    rounded corners = 10pt,
    thick,
    use as bounding box
] (-6, 7) rectangle (6, -1);
\draw[->, thick] (-6, 0) -- (6, 0) node[above left, outer sep = 3pt] {\(x\)};
\foreach \x in {-5, ..., -1, 1, 2, ..., 5}
    \draw(\x, 5pt) -- (\x, -5pt) node[below] {\(\x\)};
\draw[->, thick] (0, -1) -- (0, 7) node[below right, outer sep = 3pt] {\(y\)};
\foreach \y in {1, ..., 6}
    \draw (5pt, \y) -- (-5pt, \y) node[left] {\(\y\)};
\draw[blue, ultra thick] plot[domain = -2.5:2.5, smooth] (\x, {\x * \x + $a});
END_TIKZ

$altText =
    "graph of a parabola with vertex at (0, $a) and "
    . 'passing through the point (1, '
    . ($a + 1) . ')';

Setup

A LayoutTable is meant to be used for layout, i.e., to organize various HTML elements nicely for display. It is not meant to be used to display organized data. If a table that displays organized data is needed use DataTable instead. See Data Table for an example of the usage of the DataTable method.

Typically the PGML syntax for a DataTable should be used as is done in this example. However, the result of calling DataTable could also be used. It is called as follows.

$table = LayoutTable(
    [
        [row1],
        [row2],
        ...
        [rowN]
    ],
    options
);

where the data goes in as an array reference of array references. Some of the DataTable options are demonstrated here, but the full list of options and explanation of there usage is in the niceTables.pl documentation

Then the table would be inserted into the problem text by adding [$table]* in the desired location inside the BEGIN_PGML/END_PGML block.

In this example a table with one row and two columns is created. The primary text of the problem and answer will be in the left column, and the image will be displayed in the right column. In the setup the answer and the image are defined.

BEGIN_PGML
[#
    [.
        A common situation is that there is a problem with a graph and
        the problem is in the left column and the graph is in the right
        column.

        This even works with an equation like [`e^{i\pi} + 1 = 0`].

        Answer rules can also be added.

        A formula for the function graphed on the right is
        [`f(x) =`] [_]{$ans}{10}.
    .]
    [.[![$altText]!]{$graph}{400}{ image_options => { tex_size => 600 } }.]
#]*{ align => 'lc' }
END_PGML

Statement

The PGML syntax for inserting a LayoutTable is [# ... #]*{ options }. Note that it is the * after #] that makes this a LayoutTable as opposed to a DataTable. In between [# and #]* any number of cells can be added with [. ... .]. The end of a row is marked by adding a * to the end of the last cell in the row (the * can be omitted on the last row and since this example only has one row, none of these are needed). Inside of a cell started with [. and ended with .] all of the usual PGML syntax can be used.

Options can also be passed to a cell with [. ... .]{ options }. This example does not use any cell options.

ANS($ans->cmp);

Answer

Since ans_rule is used to produce answer blanks, this in needed.
