Data Grid Print

Printing a virtualized grid straight from the browser prints the twenty rows that happen to be in the DOM, and a paginated one prints the current page. Neither is what anyone means by “print this table”, so the grid renders a plain, complete table, prints that, and throws it away.

Print

Enable the toolbar action with toolbar: { print: true }, or call print() on the instance from your own button. Search the grid below, then print: the printout carries every matching row, not just the visible ones.

<div id="dataGridPrint"></div>

new coreui.DataGrid(document.getElementById('dataGridPrint'), {
  columns: [
    { key: 'name', label: 'Name' },
    { key: 'role', label: 'Role' },
    { key: 'country', label: 'Country' }
  ],
  items: Array.from({ length: 60 }, (_, index) => ({
    name: `Person ${index + 1}`,
    role: index % 3 === 0 ? 'admin' : 'user',
    country: ['Poland', 'Germany', 'Spain', 'Italy'][index % 4]
  })),
  printTitle: 'Team roster',
  toolbar: { print: true, search: true },
  globalFilter: true
})

What gets printed

• Every sorted and filtered row. Pagination and virtualization are display concerns; the printout is the whole result set the user’s sorting, filters and search produced.
• The visible columns, in their current order — hidden and reordered columns follow what is on screen.
• Values as displayed. A column’s formatter runs first, so a formatted date prints as the date on screen.
• The printTitle as a heading above the table, when set.

Custom cell renderers are not carried into the printout: it is built from values as text, never from markup, so the printed page can never become an injection surface for the data.

Options

Styling the printout

The clone is a .data-grid-print-root element appended to the document, and the print stylesheet hides everything else on the page while it is there. Restyle it like any other markup:

@media print {
  .data-grid-print-root h1 { font-size: 1rem; }
  .data-grid-print-root :is(th, td) { border-color: #999; }
}
