toHTML
Edit page Last modified: 14 January 2025DataFrame can be rendered to HTML. Rendering of hierarchical tables in HTML is supported by JS and CSS definitions that can be found in project resources.
Depending on your environment there can be different ways to use result of toHTML functions
IntelliJ IDEA
Working with result
The following function produces HTML that includes JS and CSS definitions. It can be displayed in the browser and has parameters for customization.
df.toStandaloneHTML(DisplayConfiguration(rowsLimit = null)).openInBrowser()
df.toStandaloneHTML(DisplayConfiguration(rowsLimit = null)).writeHTML(File("/path/to/file"))
df.toStandaloneHTML(DisplayConfiguration(rowsLimit = null)).writeHTML(Path("/path/to/file"))Composing multiple tables
toHTML and toStandaloneHTML return composable DataFrameHtmlData. You can use it to include additional scripts, elements, styles on final page or just merge together multiple tables.
val df1 = df.reorderColumnsByName()
val df2 = df.sortBy { age }
val df3 = df.sortByDesc { age }
listOf(df1, df2, df3).fold(DataFrameHtmlData.tableDefinitions()) { acc, df -> acc + df.toHTML() }Jupyter Notebooks
Configuring display for individual output
toHTML is useful if you want to configure how a single cell is displayed. To configure the display for the entire notebook, please refer to Jupyter Notebooks section.
df.toHTML(DisplayConfiguration(cellContentLimit = -1))
