| Syntax | HTML syntax - This element does not require a closing tag.
<col> XHTML syntax - This element is opened and closed, within a single tag, by adding a space followed by a forward slash at the end of the tag. <col /> |
|---|---|
| Usage | The <col> tag is used to specify column attributes within a table. If used, place the <col> tag before any <thead>, <tfoot>, <tbody>, or <tr> tags within the table. Also, if a <caption> tag is used, the <col> tag should occur after it. A table can contain a separate <col> tag for each column. Using the span attribute, a single <col> tag can apply to more than one column. HTML Example using one <col> tag for each column. <table border="1"> <caption>Stock Tracker</caption> <col width="200"> <col width="300"> <tr> <th>Stock Symbol</th> <th>Profit</th> </tr> <tr> <td>MSFT</td> <td>$723.48</td> </tr> <tr> <td>GOOG</td> <td>$1254.58</td> </tr> </table>  XHTML Example using one <col> tag for each column. <table border="1"> <caption>Stock Tracker</caption> <col width="200" /> <col width="300" /> <tr> <th>Stock Symbol</th> <th>Profit</th> </tr> <tr> <td>MSFT</td> <td>$723.48</td> </tr> <tr> <td>GOOG</td> <td>$1254.58</td> </tr> </table>  |
| Content Model | The <col> element cannot contain any tags. |

| Attribute | Description |

| align | The align attribute specifies the horizontal alignment within a cell. Possible values are "center", "char", "justify", "left", and "right". |
| char | The char attribute specifies a single character to act as an alignment character when the align attribute is set to "char". The default character for this attribute is the decimal point. Note: This attribute may have little or no browser support among popular browsers. |
| charoff | The charoff attribute specifies an offset to the first occurrence of the alignment character, which is specified by the char attribute. Note: This attribute may have little or no browser support among popular browsers. |
| span | The span attribute specifies the number of columns that the <col> tag applies to. HTML Example using a single <col> tag for multiple columns by using the span attribute. <col span="2" width="200">XHTML Example using a single <col> tag for multiple columns by using the span attribute. <col span="2" width="200" /> |
| valign | The valign attribute specifies the vertical alignment within a cell. Possible values are "baseline", "bottom", "middle", and "top". |
| width | The width attribute specifies the default column width. The value of the width attribute can be specified in pixels, percentage, or relative size. HTML <col> tag example using pixels: <col width="300">
HTML <col> tag example using percentage: <col width="30%">
HTML <col> tag example using relative size: <col width="2*">
HTML <col> tag example using relative size to set the width to match the column's contents: <col width="0*">
XHTML <col> tag example using pixels: <col width="300" />
XHTML <col> tag example using percentage: <col width="30%" />
XHTML <col> tag example using relative size: <col width="2*" />
XHTML <col> tag example using relative size to set the width to match the column's contents: <col width="0*" /> |
| id | The id attribute assigns a unique name to a tag. This allows style sheets or scripts to reference the tag. See id Example |
| class | The class attribute assigns a class name to a tag. The class name does not need to be unique. More than one tag can have the same class name. This allows style sheets or scripts to reference multiple tags with a single class name. See class Example |
| style | The style attribute specifies styles for the tag. For Cascading Style Sheets (CSS), the syntax is name:value. Each name:value pair is separated by semicolons. See style Example |
| title | The title attribute specifies additional information about the tag. It is common for browsers to display the title when the pointing device stops over the object. See title Example |
| onclick | The onclick attribute specifies a script to be run when the object is clicked with a mouse or other pointing device. See onclick Example |
| ondblclick | The ondblclick attribute specifies a script to be run when the object is double clicked with a mouse or other pointing device. See ondblclick Example |
| onkeydown | The onkeydown attribute specifies a script to be run when a key is pressed down. See onkeydown Example |
| onkeypress | The onkeypress attribute specifies a script to be run when a key is pressed and released. See onkeypress Example |
| onkeyup | The onkeyup attribute specifies a script to be run when a key is released. See onkeyup Example |
| onmousedown | The onmousedown attribute specifies a script to be run when the mouse button, or other pointing device button, is pressed while over the object. See onmousedown Example |
| onmousemove | The onmousemove attribute specifies a script to be run when the mouse, or other pointing device, is moved while it is over the object. See onmousemove Example |
| onmouseout | The onmouseout attribute specifies a script to be run when the mouse, or other pointing device, is moved away from an object after being over it. See onmouseout Example |
| onmouseover | The onmouseover attribute specifies a script to be run when the mouse, or other pointing device, is moved onto the object. See onmouseover Example |
| onmouseup | The onmouseup attribute specifies a script to be run when the mouse button, or other pointing device button, is released while over the object. See onmouseup Example |
| dir | The dir attribute tells the browser whether the text should be displayed from left-to-right or right-to-left. It does not reverse the direction of the characters, like the <bdo> tag does, but it can help the browser to determine if the text should be aligned on the left side or the right side. See dir Example |
| lang | The lang attribute specifies a language. This attribute can help the browser to correctly display text. This attribute can also be useful for braille translation software, speech synthesizers, dictionary definitions, etc. See lang Example |
| xml:lang | The xml:lang attribute specifies a language for XHTML documents. This attribute can help the browser to correctly display text. This attribute can also be useful for braille translation software, speech synthesizers, dictionary definitions, etc. See xml:lang Example Note: XHTML only. |
