Table / Pagination / Groups

Use a paginated table to display large (100k+ rows) tabular data managed in custom groups.

from h2o_wave import main, app, Q, ui
groups = [ui.table_group(f"Group-{i + 1}", [    ui.table_row(name=f"row{i * 3 + 1}", cells=[f"Item-{i * 3 + 1}"]),    ui.table_row(name=f"row{i * 3 + 2}", cells=[f"Item-{i * 3 + 2}"]),    ui.table_row(name=f"row{i * 3 + 3}", cells=[f"Item-{i * 3 + 3}"]),]) for i in range(100)]groups_per_page = 10

@app('/demo')async def serve(q: Q):    if not q.client.initialized:        q.page['form'] = ui.form_card(box='1 1 -1 -1', items=[            ui.table(                name='table',                columns=[ui.table_column(name='text', label='Text', link=False)],                groups=groups[0:groups_per_page],                pagination=ui.table_pagination(total_rows=len(groups), rows_per_page=groups_per_page),                height='590px',                events=['page_change']            )        ])        q.client.initialized = True
    if q.events.table and q.events.table.page_change:        offset = q.events.table.page_change.get('offset', 0)        new_groups = groups[offset:offset + groups_per_page]        q.page['form'].items[0].table.groups = new_groups
