Remarks
Use the HtmlTableRowCollection class to programmatically manage a collection of HtmlTableRow objects that represent the rows in an HtmlTable control. This class is commonly used to add, remove, or modify the contents of a row in an HtmlTable control.
Note An HtmlTable control contains a Rows property that represents a collection of HtmlTableRow objects. Each HtmlTableRow represents an individual row in the table. An HtmlTableRow contains a Cells property that represents a collection of HtmlTableCell objects. These objects, in turn, represent the individual cells of the table. To retrieve an individual cell, first get the HtmlTableRow, representing the row containing the cell, from the Rows collection of the HtmlTable control. You can then get the HtmlTableCell, representing the cell in the row, from the Cells collection of the HtmlTableRow.
Example
[Visual Basic, C#, JScript] The following example demonstrates how to dynamically generate the contents of an HtmlTable control by adding rows to an HtmlTableRowCollection. Notice that the Rows property of a table is the HtmlTableRowCollection.
