Table to HTML String

This Node Is Deprecated — This version of the node has been replaced with a new and improved version. The old version is kept for backwards-compatibility, but for all new workflows we suggest to use the version linked below.

KNIME is able to render HTML in the String renderer. Converts the input table into an a single HTML String which can then be rendered in an HTML viewer. This string could for example be used in the email node, or added into another table for visualisation of small tables in a single cell.

The rendered HTMl will also be added as a flow variable "html-content" which can be accessed using the flow variable port.

Options

Number of rows: The maximum number of rows to add to the HTML table. Further rows are dropped.
Include RowID: Should a column be added for the RowID
Format double: When true uses the DecimalFormater to format the double. An example default value is given.
Decimal format string: The string to use for double formatting when "Format double" is true
Column selection: Which columns should be added to the table. Must implement IntValue, DoubleValue or StringValue
Add basic style: Adds some basic inline CSS styles to the table. Black header row with white text, alternating white and grey row backgrounds and grey cell borders. This will render nicer in emails but poorly in KNIME tables.
