    • Table Binding
      • Using table data binding, each record can be displayed in a different row of a table. The syntax is:
      • <table datasrc=“# id ”>
      • <tr>
      • <td><span datafld=“ field1 ”></span></td>
      • <td><span datafld=“ field2 ”></span></td>
      • </tr>
      • </table>
    • Table Binding
      • In the example, id is the name of the data island, field1, field2 are the fields from the recordset.
    • Page Binding
      • As you add more records to your XML document, a table can become long and unwieldy. One way to fix this is to give the user the option of limiting the number of records displayed at any one time.
      • The user can then move forward of backward that number of records at a time. This is called paging .
    • Page Binding
      • To specify the page size, add the dataPageSize attribute to the <table> tag:
        • dataPageSize=“ number ”
      • number is the number of records you want displayed in a single page.
    • Navigating a Table Page
      • A unique identifier must be assigned to a table using the ID attribute before writing a command to navigate a table page. The syntax to do this is:
        • <table id=“ id”>
      • Here, id is the name you assign to the table object.
      • This is needed because the commands to navigate the table pages act on the table itself not the recordset.
    • Table Methods and Properties
      • These figures show some table methods and properties
    • Table Methods and Properties
      • To run these commands, add the command to the onClick event handler of a <button> tag. For example, to move to the last page in a data table named “StaffTable”, you enter the attribute:
        • onClick=“StaffTable.lastPage( )”
    • Hierarchical Records
      • This figure shows the layout of the EMP2.XML document
    • Hierarchical Records
      • To bind the Employee fields in the previous slide to a table, you create a table as follows:
      • <table datasrc=“#Staff_Info” datafld=“Employee”>
      • <tr>
      • <td><span datafld=“Name”></span></td>
      • <td><span datafld=“Position”></span></td>
      • <td><span datafld=“Phone”></span></td>
      • </tr>
      • </table>
