Category

Data output tags

Syntax

<cfcol 
    header = "column header text"
    text = "column text"
    align = "left|right|center"
    width = "number that indicates width of column">

Note: You can specify this tag's attributes in an attributeCollection attribute whose value is a structure. Specify the structure name in the attributeCollection attribute and use the tag's attribute names as structure keys.

History

ColdFusion MX: Added the ability to construct dynamic cfcol statements.

Attribute

Req/Opt

Default

Description

header

Required

 

Column header text. To use this attribute, you must also use the cftable colHeaders attribute.

text

Required

 

Double-quotation mark-delimited text; determines what to display. Rules: same as for cfoutput sections. You can embed hyperlinks, image references, and input controls.

align

Optional

left

Column alignment:

  • left
  • right
  • center

width

Optional

20

Column width. If the length of data displayed exceeds this value, data is truncated to fit. To avoid this, use an HTML table tag.

If the surrounding cftable tag includes the htmltable attribute, width specifies the percent of the table width and it does not truncate text; otherwise, width specifies the number of characters.

Usage

At least one cfcol tag is required within the cftable tag. You must put cfcol and cftable tags adjacent in a page. The only tag that you can nest within the cftable tag is the cfcol tag. You cannot nest cftable tags.

To display the cfcol header text, you must specify the cfcol header and the cftable colHeader attribute. If you specify either attribute without the other, the header does not display. No error is thrown.

Example

<!--- This example shows the use of cfcol and cftable to align 
    information returned from a query. --->
<!--- Query selects information from cfdocexamples data source. --->
<cfquery name = "GetEmployees" dataSource = "cfdocexamples">
    SELECT Emp_ID, FirstName, LastName, EMail, Phone, Department
    FROM Employees
</cfquery>
<html>
<body>
<h3>cfcol Example</h3>
<!--- Uses the HTMLTable attribute to display cftable as an HTML 
    table, rather than PRE formatted information --->
<cftable 
    query = "GetEmployees" 
    startRow = "1" colSpacing = "3" 
    HTMLTable colheaders>
<!--- Each cfcol tag sets the width of a column in the table, 
    the header information, and the text/CFML for the cell. --->
    <cfcol header = "<b>ID</b>"
        align = "Left"
        width = 2
        text= "#Emp_ID#">
    <cfcol header = "<b>Name/Email</b>"    
        align = "Left"
        width = 15
        text= "<a href = 'mailto:#Email#'>#FirstName# #LastName#</A>">
    <cfcol header = "<b>Phone Number</b>"
        align = "Center"
        width = 15
        text= "#Phone#">
</cftable>
