<tbody>: The Table Body element

The <tbody> HTML element encapsulates a set of table rows (<tr> elements), indicating that they comprise the body of the table (<table>).

+

Try it

+
+

The <tbody> element, along with its related <thead> and <tfoot> elements, provide useful semantic information that can be used when rendering for either screen or printer.

Content categories None.
Permitted content Zero or more <tr> elements.
Tag omission A <tbody> element's start tag can be omitted if the first thing inside the <tbody> element is a <tr> element, and if the element is not immediately preceded by a <tbody>, <thead>, or <tfoot> element whose end tag has been omitted. (It can't be omitted if the element is empty.) A <tbody> element's end tag can be omitted if the <tbody> element is immediately followed by a <tbody> or <tfoot> element, or if there is no more content in the parent element.
Permitted parents Within the required parent <table> element, the <tbody> element can be added after a <caption>, <colgroup>, and a <thead> element.
Implicit ARIA role rowgroup
Permitted ARIA roles Any

Attributes

+

This element includes the global attributes.

+

Deprecated attributes

+
+align +

This enumerated attribute specifies how horizontal alignment of each cell content will be handled. Possible values are:

  • +left, aligning the content to the left of the cell
  • +center, centering the content in the cell
  • +right, aligning the content to the right of the cell
  • +justify, inserting spaces into the textual content so that the content is justified in the cell
  • +char, aligning the textual content on a special character with a minimal offset, defined by the char and charoff attributes.

If this attribute is not set, the left value is assumed.

As this attribute is deprecated, use the CSS text-align property instead.

Note: The equivalent text-align property for the align="char" is not implemented in any browsers yet. See the text-align's browser compatibility section for the <string> value.

+bgcolor +

The background color of the table. It is a 6-digit hexadecimal RGB code, prefixed by a '#'. One of the predefined color keywords can also be used.

As this attribute is deprecated, use the CSS background-color property instead.

+char +

This attribute is used to set the character to align the cells in a column on. Typical values for this include a period (.) when attempting to align numbers or monetary values. If align is not set to char, this attribute is ignored.

+charoff +

This attribute is used to indicate the number of characters to offset the column data from the alignment characters specified by the char attribute.

+valign +

This attribute specifies the vertical alignment of the text within each row of cells of the table header. Possible values for this attribute are:

  • +baseline, which will put the text as close to the bottom of the cell as it is possible, but align it on the baseline of the characters instead of the bottom of them. If characters are all of the size, this has the same effect as bottom.
  • +bottom, which will put the text as close to the bottom of the cell as it is possible;
  • +middle, which will center the text in the cell;
  • and top, which will put the text as close to the top of the cell as it is possible.

As this attribute is deprecated, use the CSS vertical-align property instead.

Usage notes

+

Examples

+

Below are some examples showing the use of the <tbody> element. For more examples of this element, see the examples for <table>.

+

Basic example

+
+

In this relatively simple example, we create a table containing information about a group of students with a <thead> and a <tbody>, with a number of rows in the body.

HTML

The table's HTML is shown here. Note that all the body cells including information about students are contained within a single <tbody> element.

+

html

+
<table>
+  <thead>
+    <tr>
+      <th>Student ID</th>
+      <th>Name</th>
+      <th>Major</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>3741255</td>
+      <td>Jones, Martha</td>
+      <td>Computer Science</td>
+    </tr>
+    <tr>
+      <td>3971244</td>
+      <td>Nim, Victor</td>
+      <td>Russian Literature</td>
+    </tr>
+    <tr>
+      <td>4100332</td>
+      <td>Petrov, Alexandra</td>
+      <td>Astrophysics</td>
+    </tr>
+  </tbody>
+</table>
+
+

CSS

The CSS to style our table is shown next.

+

css

+
table {
+  border: 2px solid #555;
+  border-collapse: collapse;
+  font:
+    16px "Lucida Grande",
+    "Helvetica",
+    "Arial",
+    sans-serif;
+}
+
+

First, the table's overall style attributes are set, configuring the thickness, style, and color of the table's exterior borders and using border-collapse to ensure that the border lines are shared among adjacent cells rather than each having its own borders with space in between. font is used to establish an initial font for the table.

+

css

+
th,
+td {
+  border: 1px solid #bbb;
+  padding: 2px 8px 0;
+  text-align: left;
+}
+
+

Then the style is set for the majority of the cells in the table, including all data cells but also those styles shared between our <td> and <th> cells. The cells are given a light gray outline which is a single pixel thick, padding is adjusted, and all cells are left-aligned using text-align

+

css

+
thead > tr > th {
+  background-color: #cce;
+  font-size: 18px;
+  border-bottom: 2px solid #999;
+}
+
+

Finally, header cells contained within the <thead> element are given additional styling. They use a darker background-color, a larger font size, and a thicker, darker bottom border than the other cell borders.

Result

The resulting table looks like this:

+
+ + +
+
+

Multiple bodies

+
+

You can create row groupings within a table by using multiple <tbody> elements. Each may potentially have its own header row or rows; however, there can be only one <thead> per table! Because of that, you need to use a <tr> filled with <th> elements to create headers within each <tbody>. Let's see how that's done.

Let's take the previous example, add some more students to the list, and update the table so that instead of listing each student's major on every row, the students are grouped by major, with heading rows for each major.

Result

First, the resulting table, so you know what we're building:

+
+ + +

HTML

The revised HTML looks like this:

+

html

+
<table>
+  <thead>
+    <tr>
+      <th>Student ID</th>
+      <th>Name</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <th colspan="2">Computer Science</th>
+    </tr>
+    <tr>
+      <td>3741255</td>
+      <td>Jones, Martha</td>
+    </tr>
+    <tr>
+      <td>4077830</td>
+      <td>Pierce, Benjamin</td>
+    </tr>
+    <tr>
+      <td>5151701</td>
+      <td>Kirk, James</td>
+    </tr>
+  </tbody>
+  <tbody>
+    <tr>
+      <th colspan="2">Russian Literature</th>
+    </tr>
+    <tr>
+      <td>3971244</td>
+      <td>Nim, Victor</td>
+    </tr>
+  </tbody>
+  <tbody>
+    <tr>
+      <th colspan="2">Astrophysics</th>
+    </tr>
+    <tr>
+      <td>4100332</td>
+      <td>Petrov, Alexandra</td>
+    </tr>
+    <tr>
+      <td>8892377</td>
+      <td>Toyota, Hiroko</td>
+    </tr>
+  </tbody>
+</table>
+
+

Notice that each major is placed in a separate <tbody> block, the first row of which contains a single <th> element with a colspan attribute that spans the entire width of the table. That heading lists the name of the major contained within the <tbody>.

Then each remaining row in each major's <tbody> consists of two cells: the first for the student's ID and the second for their name.

CSS

Most of the CSS is unchanged. We do, however, add a slightly more subtle style for header cells contained directly within a <tbody> (as opposed to those which reside in a <thead>). This is used for the headers indicating each table section's corresponding major.

+

css

+
tbody > tr > th {
+  background-color: #dde;
+  border-bottom: 1.5px solid #bbb;
+  font-weight: normal;
+}
