1.8

Before you can add an ID or class to a table, row or cell, you have to select that table, row or
cell (see "Selecting a table, row or cell" on page218). After selecting the cell, row or table, type
the ID or class in the respective field on the Attributes pane.
In CSS, refer to the table, row or cell with #ID (where ID should be replaced with the actual ID)
or with .class (where class should be replaced with the actual class).
Styling the first, last and nth rows
The CSS pseudo-classes :first-child, :last-child and :nth-child() are very useful for
styling table rows.
A CSS pseudo-class follows a selector to specify a special state of that selector. It always
starts with a colon.
The pseudo-classes :first-child, :last-child and :nth-child() select an element only if it
is the first, last or nth child element respectively. (In HTML and CSS, the word child refers to an
element inside another element.)
The following CSS style rule selects the table row (tr) that comes first (:first-child) in its parent
(which naturally is a table), and colors its background red:
tr:first-child {
background: red;
}
Tip
In a Dynamic Table, data are in the body of the table (selector: tbody) and subtotals are in the footer
(selector: tfoot).
Selecting a specific row, odd or even rows, or every nth row
The pseudo-class :nth-child() lets you select a specific row, all odd or even rows, or every
nth row.
