Build the HTML table preview for one page — build_html

Pure presentation: renders an already-materialized page of data as the blockr table preview (header with column names, labels and type tags, pillar-formatted cells, NA / negative styling, footer with row range and prev / next pagination). Data access (sorting, pagination, lazy tables) is handled by table_page().

Usage

build_html_table(
  dat,
  total_rows,
  sort_state = NULL,
  ns = NULL,
  page = 1L,
  page_size = 5L,
  table_label = NULL,
  sort_input = NULL,
  page_input = NULL,
  has_more = NULL,
  cache = NULL
)

Arguments

dat: Materialized data frame holding only the rows of the current page.
total_rows: Total number of rows in the full result (drives the row-range text and pagination).
sort_state: List with elements col and dir ("asc", "desc", "na" or "none") or NULL.
ns: Optional namespace function used for the legacy default input ids when sort_input / page_input are not supplied.
page: Current page (1-based).
page_size: Rows per page.
table_label: Optional table-level label shown in the footer.
sort_input, page_input: Full (already namespaced) ids of the Shiny inputs receiving sort and page events. Supply per-instance ids when a session shows more than one preview; when NULL the legacy shared names blockr_table_sort / blockr_table_page are used.
has_more: Look-ahead flag used when total_rows is NA (remote / lazy tables that are never counted): TRUE signals that rows exist beyond the current page, which keeps the next button enabled and shows the "of many" row-range text instead of a known total.
cache: Optional environment memoizing the column widths across renders of the same result (keyed on the column names). Pass the same per-result cache used for table_page() so sorting and paging emit identical widths and the columns never reflow. When NULL, widths are recomputed from the current page on every render.

Value

A shiny::tagList() with the table preview, carrying the table_preview_dep() html dependency.
