A caracter that will act as axis for text alignment. It's meant to work together with the align attribute when it has the "char" value. In other situations it will be completely ignored. This attribute has become obsolete in HTML 5 and its use is consequently invalid. Authors are adviced to replace it with style sheet declarations. An offset, from the first occurrence of the alignment caracter specified in the char attribute and in the direction of the text.
The resulting character of this calculation will be the axis for text alignment. For this attribute to be considered, the align attribute's value must be "char" and the char attribute must be present.
This attribute is considered obsolete by HTML 5 and its use is no longer recommended. Report Error. Your message has been sent to W3Schools. W3Schools is optimized for learning and training.

Those changes make the HTML look like this:. The differences that matter here—for the purposes of discussing row and column spans—are in the first few lines of the code above. Note the use of rowspan on to make the "Name", "ID", and "Balance" headers occupy two rows instead of just one, and the use of colspan to make the "Membership Dates" header cell span across two columns. Before really getting into styling this table, let's take a moment to add row and column groups to help make our CSS easier.
The output is entirely unchanged, despite the addition of useful contextual information under the hood:. As is the case with all parts of a table, you can change the appearance of a table row and its contents using CSS.
Let's apply a basic style to the table to adjust the typeface being used, and add a background color to the header row. This is a way to quickly apply a background color to all of the cells in the heading area at once. Now we'll go all-out, with styles on rows in the header and body areas both, including alternating row colors, cells with different colors depending on position within a row, and so forth.
The CSS is much more involved this time. It's not complicated, but there's a lot going on. Let's break it down. Here we've added the border-spacing and border-collapse properties to eliminate spacing between cells and collapse borders that touch one another to be a single border instead of winding up with double borders.
Then we set the bottom border of the top header to be a two-pixel wide line. Notice, however, that we're using the :nth-of-type selector to apply border-bottom to the second row in the heading. Because the heading is made of two rows that are spanned by some of the cells. That means there are actually two rows there; applying the style to the first row would not give us the expected result.
Let's style these two header cells with green and red hues to represent the "good" of a new member and the "bummer" of a canceled membership.
