- 2. What is a TABLE? • The HTML table allows web designers to arrange & organize data -- text, images, hyperlinks, forms, form fields, other tables, etc. • Tables are made up of rows and columns. --Rows are horizontally arranged cells --Columns are vertically arranged cells 1 ROW 1 COLUMN Author: M.Rehan
- 3. TABLE: Components • Basic HTML table tags: o <table></table> required oDefines the beginning and end of the table o <tr></tr> required oTable Row - Defines the beginning and end of a horizontal row. o <td></td> required oTable Cell - Defines an individual cell. Cells are always placed inside a row. “td” stands for table data. Code <table> <tr><td>1</td><td>2</td></tr> <tr><td>3</td><td>4</td></tr> </table> 1 2 3 4 Browser View Author: M.Rehan
- 4. TABLE: Components Cont. • Additional HTML table tags: o <th></th> optional o Defines a table header row. Used instead of “td.” o Text is bold & centered within the cell o <caption></caption> optional o Sets a caption for the table. Goes after the table tag but not inside “tr” or “td.” There should be only one caption per table. Appears centered above the table. Code <table> <caption>My Schedule</caption> <tr><th>Period</th><th>Class</th></tr> <tr><td>1st</td><td>PE</td></tr> <tr><td>2nd</td><td>Math</td></tr> </table> Period Class 1st PE 2nd Math Browser View My Schedule Author: M.Rehan
- 5. TABLE: Tag attributes • Attributes that can be added to table tags: o Table Border optional o Table border attribute dictates border thickness o Example: <table border=“1”> o 0 = no border & larger numbers = thicker borders o No border defined = no border viewable o bordercolor can be added to change the color of the table border. Border must be >0 to see the color o Example: <table border=“1” bordercolor=“red”> o Table Width & Height optional o Width & Height can be defined in the open table tag o Example: <table width=“100” height=“100”> o The height attribute is widely supported, but isn't actually part of the official HTML standard. It may not always work as you expect. o If no size values are specified, the browser will decide on an appropriate size. Results will vary between browsers.
- 6. TABLE: Tag attributes cont. • Additional attributes that can be added to table tags: o Cell Padding optional o Defines the space inside each cell, i.e. the space between the edges of the cell and the content within it. o Example: <table border=“1” cellpadding=“10” bordercolor=“red”> o Cell Spacing optional o Defines the space between cells. If a border is used, the spacing will widen the border. o Example: <table border=“1” cellspacing=“10” bordercolor=“green”> o These attributes apply to the entire table - you can't specify spacing or padding for individual cells.
- 7. TABLE: Tag attributes cont. • Attributes that can be added to th, tr, & td tags: o Alignment optional o Alignment can be added to the table, tr, th, & td tag. o If applied to the table tag, the entire table will align. o If applied to the tr tag, the entire row will align. o If applied to the th or td tag, just the cell will align. o Alignment options: left, center, & right o Contents will left align by default Code <table border=“1”><tr align=“right”> <td>Test1</td><td>Test2</td></tr><tr> <td>Test3</td><td>Test4</td></tr></table> o Column & Row span optional o Column span (colspan) is added to a th or td tag o Row span (rowspan) can added to the tr tag Code <table><tr><td colspan=2>Heading</td></tr> <tr><td>Entry1</td><td>Entry2</td></tr></table> Browser View Test1 Test2 Test3 Test4 Browser View Heading Entry1 Entry2
