Editing Help:Tables (section)

== XHTML attributes ==
You can add XHTML attributes to tables. For the authoritative source on these, see [http://www.w3.org/TR/REC-html40/struct/tables.html the W3C's HTML 4.01 Specification page on tables].

=== Attributes on tables ===
Placing attributes after the table start tag (<code>{|</code>) applies attributes to the entire table.

{| cellspacing="0" border="1"
!style="width:50%"|You type
!style="width:50%"|You get
|-
|
<pre>
{| border="1" align="center" style="text-align:center;"
|Orange
|Apple
|12,333.00
|-
|Bread
|Pie
|500.00
|-
|Butter
|Ice cream
|1.00
|}
</pre>
|
{| border="1" align="center" style="text-align:center;"
|Orange
|Apple
|12,333.00
|-
|Bread
|Pie
|500.00
|-
|Butter
|Ice cream
|1.00
|}
|}

=== Attributes on cells ===
You can put attributes on individual '''cells'''. For example, numbers may look better aligned right.

{| cellspacing="0" border="1"
!style="width:50%"|You type
!style="width:50%"|You get
|-
|
<pre>
{| border="1"
|Orange
|Apple
|align="right" | 12,333.00
|-
|Bread
|Pie
|align="right" | 500.00
|-
|Butter
|Ice cream
|align="right" | 1.00
|}
</pre>
|
{| border="1"
|Orange
|Apple
|align="right"|12,333.00
|-
|Bread
|Pie
|align="right"|500.00
|-
|Butter
|Ice cream
|align="right"|1.00
|}
|}

You can also use '''cell''' attributes when you are listing multiple '''cells''' on a single line. Note that the '''cells''' are separated by <code>||</code>, and within each '''cell''' the attribute(s) and value are separated by <code>|</code>.

{| cellspacing="0" border="1"
!style="width:50%"|You type
!style="width:50%"|You get
|-
|
<pre>
{| border="1"
| Orange || Apple     || align="right" | 12,333.00
|-
| Bread  || Pie       || align="right" | 500.00
|-
| Butter || Ice cream || align="right" | 1.00
|}
</pre>
|
{| border="1"
| Orange || Apple     || align="right" | 12,333.00
|-
| Bread  || Pie       || align="right" | 500.00
|-
| Butter || Ice cream || align="right" | 1.00
|}
|}

===Attributes on rows===
You can put attributes on individual '''rows''', too.

{| cellspacing="0" border="1"
!style="width:50%"|You type
!style="width:50%"|You get
|-
|
<pre>
{| border="1"
|Orange
|Apple
|align="right"|12,333.00
|-
|Bread
|Pie
|align="right"|500.00
|- style="font-style:italic; color:green;"
|Butter
|Ice cream
|align="right"|1.00
|}
</pre>
|
{| border="1"
|Orange
|Apple
|align="right"|12,333.00
|-
|Bread
|Pie
|align="right"|500.00
|- style="font-style:italic; color:green;"
|Butter
|Ice cream
|align="right"|1.00
|}
|}

====Simple one-pixel table border====
The default table formatting uses the "border-collapse: separate" model, which adds table cell spacing (which also separates the table outer border from its content cells). Even with a zero cellspacing, the borders of consecutive cells (and of the overall table container) will add up, so to get a one-pixel separation between cells, you need to selectively remove one or more of the four borders of cells.

Such tables may be formatted more simply, using the "border-collapse: collapse" CSS property; in this table formatting model, the cellspacing attribute (or the CSS "border-spacing:" property) and the table's "padding:" CSS property is ignored and only the larger border of adjacent inner cells (or the table border for outer cells) will be used.

An example of the above for one-pixel table border, using each model (without need for external extensions):

{|border="1" cellspacing="0" cellpadding="2"
|-
!|You type
!width="200"|You get
|-
|
<pre style="font-size: 80%">
{|style="border-collapse: separate; border-spacing: 0; border-width: 1px; border-style: solid; border-color: #000; padding: 0"
|-
!style="border-style: solid; border-width: 0 1px 1px 0"| Orange
!style="border-style: solid; border-width: 0 0 1px 0"| Apple
|-
|style="border-style: solid; border-width: 0 1px 0 0"| Bread
|style="border-style: solid; border-width: 0"| Pie
|}
</pre>
|
{|style="margin: 0; border-collapse: separate; border-spacing: 0; border-width: 1px; border-style: solid; border-color: #000; padding: 0"
|-
!style="border-style: solid; border-width: 0 1px 1px 0"| Orange
!style="border-style: solid; border-width: 0 0 1px 0"| Apple
|-
|style="border-style: solid; border-width: 0 1px 0 0"| Bread
|style="border-style: solid; border-width: 0"| Pie
|}
|-
|
<pre style="font-size: 80%">
{|style="border-collapse: collapse; border-width: 1px; border-style: solid; border-color: #000"
|-
!style="border-style: solid; border-width: 1px"| Orange
!style="border-style: solid; border-width: 1px"| Apple
|-
|style="border-style: solid; border-width: 1px"| Bread
|style="border-style: solid; border-width: 1px"| Pie
|}
</pre>
|
{|style="border-collapse: collapse; border-width: 1px; border-style: solid; border-color: #000"
|-
!style="border-style: solid; border-width: 1px"| Orange
!style="border-style: solid; border-width: 1px"| Apple
|-
|style="border-style: solid; border-width: 1px"| Bread
|style="border-style: solid; border-width: 1px"| Pie
|}
|}

Notes :
* When using the "border-width:" CSS shortcut property, the order of the four space-separated specified values is: top, right, bottom, left. As an example from above: 
::"border-width: 0 1px 0 0" 
:When there are fewer than 4 values, the value for left takes its default from the value for right, the value for bottom takes its default from the value for top, and the value for right takes its default from the value for top.
* The HTML attributes (such as "width=", "border=", "cellspacing=", "cellpadding=") do not need any length unit (the pixel unit is assumed). The CSS style properties (which override the HTML attributes) require an explicit length unit (if the value is not 0) such as "px" for the pixel.

===HTML colspan and rowspan===

You can use HTML '''colspan''' and '''rowspan''' attributes on cells for advanced layout.

{| cellspacing="0" border="1"
!style="width:50%"|You type
!style="width:50%"|You get
|-
|
<pre>
{| border="1"
!colspan="6"|Shopping List
|-
|rowspan="2"|Bread & Butter
|Pie
|Buns
|Danish
|colspan="2"|Croissant
|-
|Cheese
|colspan="2"|Ice cream
|Butter
|Yoghurt
|}
</pre>
|
{| border="1"
!colspan="6"|Shopping List
|-
|rowspan="2"|Bread & Butter
|Pie
|Buns
|Danish
|colspan="2"|Croissant
|-
|Cheese
|colspan="2"|Ice cream
|Butter
|Yoghurt
|}
|}

===With HTML attributes and CSS styles===
[[Manual:CSS|CSS]] style attributes can be added with or without other HTML attributes.

{| cellspacing="0" border="1"
!style="width:50%"|You type
!style="width:50%"|You get
|-
|
<pre style="white-space:-moz-pre-wrap; white-space:-pre-wrap; white-space:-o-pre-wrap; white-space:pre-wrap; word-wrap:break-word; word-break:break-all;">
{| style="color:green; background-color:#ffffcc;" cellpadding="10" cellspacing="0" border="1"
|Orange
|Apple
|-
|Bread
|Pie
|-
|Butter
|Ice cream 
|}
</pre>
|
{| style="color:green; background-color:#ffffcc;" cellpadding="10" cellspacing="0" border="1"
|Orange
|Apple
|-
|Bread
|Pie
|-
|Butter
|Ice cream 
|}
|}

'''Attributes''' can be added to the caption and headers as follows.

{| cellspacing="0" border="1"
!style="width:50%"|You type
!style="width:50%"|You get
|-
|
<pre style="white-space:-moz-pre-wrap; white-space:-pre-wrap; white-space:-o-pre-wrap; white-space:pre-wrap; word-wrap:break-word; word-break:break-all;">
{| border="1" cellpadding="20" cellspacing="0"
|+ align="bottom" style="color:#e76700;" |''Food complements''
|-
|Orange
|Apple
|-
|Bread
|Pie
|-
|Butter
|Ice cream 
|}
</pre>
|
{| border="1" cellpadding="20" cellspacing="0"
|+ align="bottom" style="color:#e76700;" |''Food complements''
|-
|Orange
|Apple
|-
|Bread
|Pie
|-
|Butter
|Ice cream 
|}
|}

===Accessibility of table header cells===
Table header cells do not explicitly specify which table data cells they apply to (those on their right on the same row, or those below them on the same column). When the table is rendered in a visual 2D environment, this is usually easy to infer.

However when tables are rendered on non-visual medias, you can help the browser to determine which table header cell applies to the description of any selected cell (in order to repeat its content in some accessibility helper) using a scope="row" or scope="col" attribute on table header cells. In most cases with simple tables, you'll use scope="col" on all header cells of the first row, and scope="row" on the first cell of the following rows:

{| cellspacing="0" border="1"
!style="width:50%"|You type
!style="width:50%"|You get
|-
|
<pre style="white-space:-moz-pre-wrap; white-space:-pre-wrap; white-space:-o-pre-wrap; white-space:pre-wrap; word-wrap:break-word; word-break:break-all;">
{| border="1" cellspacing="0" cellpadding="2"
|-
!scope="col"| Item
!scope="col"| Quantity
!scope="col"| Price
|-
!scope="row"| Bread
| 0.3 kg
| $0.65
|-
!scope="row"| Butter
| 0.125 kg
| $1.25
|-
!scope="row" colspan="2"| Total
| $1.90
|}
</pre>
|
{| border="1" cellspacing="0" cellpadding="2"
|-
!scope="col"| Item
!scope="col"| Quantity
!scope="col"| Price
|-
!scope="row"| Bread
| 0.3 kg
| $0.65
|-
!scope="row"| Butter
| 0.125 kg
