 <h2>Horizontal alignment of cells in a column</h2>
 
+<p>A cell is similar to a block in the way its contents are rendered,
+that means, in particular, that <span
+class="propinst-text-align">'text-align'</span> applies to
+it. However, tables also allow a way of aligning text that does not
+apply to other blocks, and that is aligning the contents of several
+cells so that they all align on, e.g., a decimal point.
+
+<p>More precisely, if the value of 'text-align' for a certain cell is
+a string, that cell has an <dfn>alignment point</dfn>, which is the
+start of that string. The aligment point must be straight above or
+below the alignment points of all other cells in the same column that
+have an alignment point. (Note that the other cells do not need to
+have the same value for <span
+class="propinst-text-align">'text-align'</span>; as long as they are
+aligned on a string, they have an alignment point.)
+
+<p>Aligning text in this way is only useful if the text is short
+enough not to be broken over several lines. The result is undefined if
+the text <em>is</em> broken.
+
+<p>If the string occurs more than once in the cell's content, the
+alignment point is the start of the first occurrence.
+
+<p>If the string doesn't occur, the alignment point is the end of the
+content.
