Render a result as the HTML table preview — html_table

html_table_render() returns a shiny::renderUI() that shows result as the paginated, sortable table preview. html_table_result() is the block-flavored wrapper that reads the page_size board option first.

Usage

html_table_render(result, session, page_size = 5L)

html_table_result(result, block, session)

html_table_display

Arguments

result: A data frame or lazy table (tbl_lazy).
session: The Shiny session.
page_size: Rows per page.
block: The block object (used to read board options).

Value

A shiny::renderUI() object.

Details

html_table_display is the blockr.core::tabular_display that wires this preview into data, parser and transform blocks. Opt in per app with options(blockr.tabular_display = blockr.ui::html_table_display); the display declares and triggers on a single board option, page_size, which the HTML table reads to paginate.

Sort and page state live in the browser and arrive via Shiny inputs whose ids are derived from the output name (via shiny::getCurrentOutputInfo()), so several previews in one module session stay independent. Sorting and pagination are resolved by table_page(): in-memory frames use a cached order index, lazy dbplyr tables are counted and paged in the database.
