HTML td tag
Note: If you don't know what a tag is and/or how you must use it we recommend you to read our HTML tags and attributes tutorial that you can find in our HTML tutorials section.
Description
The
HTML td tag defines a regular cell in a table (
HTML table tag).
Attributes
The "id" attribute assigns an identifier to the associated element. This identifier must be unique in the document and can be used to refer to that element.
Example:
Code begin
<p id="paragraph1">This is the first paragraph named as paragraph1. To dynamically change its properties use this identifier.</p>Code end
The "class" attribute assigns a class name (or a list of class names separated by spaces) to the container element. It's used with style sheets and tells the browser the class to which the element is associated with. A class gives visual attributes to elements.
Example:
Code begin
<p class="references">This article is based on the book "Wind in the trees" by Jhon L. Brooks</p>
<p class="references important">This article is based on the book "Wind in the trees" by Jhon L. Brooks... and is more important than the one before.</p>Code end
Defines a visual style of this element. Is a better practice to define styles attributes in external style sheets grouping them in classes. Attributes in the "style" parameter must preserve this order "name : value" and be separated by a semi-colon.
If you're writing
XHTML code it's recommended not to use this attribute and try style sheet classes (with the "class" attribute).
Example:
Code begin
<p style="color: #0000FF; font-size: 12pt">This is a paragraph with a defined style</p>
<p>And this is another text without style.</p>Code end
Indicates a title for the element. Used to give a short description about the element that is usually shown as a "tool tip" when the user put the mouse pointer over the element.
Example:
Code |
View |
<a title="HTMLQuick.com" href="http://www.htmlquick.com">HTML code</a> |
HTML code |
Specifies the language of an element's content. The default value in "unknown".
When writing
XHTML code the syntax "xml:lang" represents a preferred alternative in XHTML 1.0 and a replacement in XHTML 1.1 (e.g., xml:lang="en").
Example:
Code begin
<p lang="en">This is a paragraph in english.</p>
<p lang="es">Este es un párrafo en español.</p>Code end
dir
Specifies the text direction of the element's contents and attribute values, as well as tables directionality. It has two possible values that are case insensitive:
- RTL: Right to left.
- LTR: Left to right.
Example:
Code begin
<q lang="he" dir="rtl">...a Hebrew quotation...</q>Code end
Defines a color to be used as a background.
align
Defines the alignment of the content of a cell. Can be one of the following values (case-insensitive):
- left: Data's aligned to the left. This is the default value for common cells (HTML td tag).
- center: Data's centered. This is the default value for table headers (HTML th tag).
- right: Data's aligned to the right.
- justify: Justified text.
- char: The text is aligned around a specific character.
Example:
Code |
View |
<table border="1" summary="Example table showing the use of the align attribute."> <tr><td style="width: 7.6em">Left</td></tr> <tr><td style="width: 7.6em" align="center">Center</td></tr> <tr><td style="width: 7.6em" align="right">Right</td></tr> </table> |
|
valign
Specifies the vertical alignment of the data in a cell. Works exactly like "align" attribute but for vertical space. The possible values are (case-insensitive):
- top: The data is aligned to the top.
- middle: The data is vertically centered. This is the default value.
- bottom: The data is aligned to the bootom.
- baseline: All the cells in a row that has this alignment should have their first text line on a baseline common to all cells in the row.
Example:
Code |
View |
<table border="1" summary="Example table showing the use of the valign attribute."> <tr> <td>1<br />2<br />3<br />4</td> <td valign="top">23.065</td> <td>324.432</td> <td valign="bottom">45.8745</td> </tr> </table> |
1 2 3 4 |
23.065 |
324.432 |
45.8745 |
|
Specifies a single character that will act as axis for text alignment.
Note: Browsers are not required to support this attribute.
Specifies the offset to the first occurrence of the alignment character on each line. Take into account the text direction (dir).
Note: Browsers are not required to support this attribute.
Contains a space-separated list of id's corresponding to other cells that provide header information for this cell.
scope
Specifies a group of cells for which this cell will provide header information. Possible values (case-insensitive):
- row: All the container row.
- col: All the container column.
- rowgroup: All the container row group.
- colgroup: All the container column group.
Provides an abbreviated version of a cell's content that may be used by browsers in some cases instead of the content itself.
Groups cells into conceptual categories that can be considered to form axes in an n-dimensional space. Browsers may provide some functionality to display and relate these categories.
Specifies the number of rows spanned by this cell. The value "0" means that spans all rows from it's position to the last row of the container section (
HTML thead tag,
HTML tbody tag or
HTML tfoot tag).
Example:
Code |
View |
<table border="1" summary="Example table showing the use of the rowspan attribute."> <tr><td rowspan="2">Cell1</td><td>Cell2</td></tr> <tr><td>Cell3</td></tr> </table> |
|
Specifies the number of columns spanned by this cell. The value "0" means that spans all columns from it's position to the last column of the container section (
HTML colgroup tag).
Example:
Code |
View |
<table border="1" summary="Example table showing the use of the colspan attribute."> <tr><td>Cell1</td><td>Cell2</td></tr> <tr><td colspan="2">Cell3</td></tr> </table> |
|
wrap
When present this boolean attribute tells the browser to don't automatically wrap text content in this cell.
Remember that boolean attributes must be defined as attr_name="attr_name" to be
XHTML code compliant.
Provides a hint of the desired with for the cell. Bowsers may change the with according to the space availability.

Examples
In this example we define a table with grouped columns, grouped rows and many attributes for each tag that will define a visual style.
