@zoos/react-table

Library of components, hooks and functions for building tables with @tanstack/react-table.

Features

`useControlledTable`

Provides fully controlled table state with performance guardrails on frequently firing events (e.g. column resizing onStateChange only fires once column resizing completes)
Sets up row models: core, expanded, faceted, filtered, sorted, grouped
Adds filter, sort functions and a few other helpful defaults to useReactTable (e.g. columnResizeMode: "onChange")

import { useControlledTable } from "@zoos/react-table";

// Controlled external table state
const [state, setState] = React.useState({} as TableState);

// Takes in same options as standard `useReactTable` except
// for the individual onStateChange handlers (e.g. onColumnVisibilityChange)
const { table } = useControlledTable({
  data,
  columns,
  state,
  onStateChange: (state) => setState(state),
});

`useVirtualization`

Hook wires up table with column and row virtualization

import { useVirtualization } from "@zoos/react-table";

const {
  // Scroll container immediately wrapping table
  scrollContainerRef,
  // Row virtualization
  rowVirtualizer,
  virtualRows,
  // Column Virtualization -
  // padding left and padding right are used to add fake columns
  columnVirtualizer,
  virtualColumns,
  virtualPaddingLeft,
  virtualPaddingRight,
} = useVirtualization({
  // Standard `Table` returned from `useReactTable`
  table,
  // `row` and `column` are standard options passed
  // to `useVirtualizer` (omitting ones defined from table)
  row: {
    // Row height in pixels - helps with scrolling smoothness
    estimateSize: () => 20,
    // How many rows to render on either side of viewport
    overscan: 5,
  },
  column: {
    // How many columns to render on either side of viewport
    overscan: 3,
  },
});

Feature Props

Tanstack Table is amazing. There are examples for everything you need (column pinning, resizing, etc.).

Unfortunately, each feature requires passing CSS rules (and other props) to each table component (<thead />, <tr />, <td />, ... ) in certain ways.

So you don't have to worry about the prop wiring for standard features, we've provided prop getters in featureProps. For styling, we used Tailwind classes (where we could) and inline styles when dynamic values were required.

If people aren't using Tailwind, we can provide a pure inline styles version or you can look at the featureProps definitions in ./packages/react-table/src/lib/feature-props and replicate.

import { featureProps, mergeFeatureProps } from "@zoos/react-table";

// Usually memoized for performance
const componentProps = React.useMemo(
  () =>
    mergeFeatureProps([
      // Row virtualization props - some feature props require data to work
      featureProps.rowVirtualization({ scrollContainerRef, rowVirtualizer }),

      // Sticky header
      featureProps.stickyHeader({
        // In most feature prop getters, you can provide custom props
        // that will be merged into that feature through the `custom`
        // field.
        //
        // For stickyHeader, `thead` is the only table component
        // affected, and therefore, the only table component that
        // can be customized.
        //
        // For stickyHeader, if you don't already have a background set
        // on `thead`, rows will show through the sticky header.
        //
        // Like stickyHeader, there are other features that require custom
        // props for them to work *fully*.
        custom: {
          thead: { className: "bg-slate-50" },
        },
      }),
      // You can also merge in your own custom styles
      {
        table: { className: "text-sm" },
        th: () => ({ className: "px-1 py-0.5" }),
        td: () => ({ className: "px-1 py-0.5" }),
      },
    ]),
  [scrollContainerRef, rowVirtualizer],
);

return (
  // Spread component props into the main table components
  <div {...componentProps.container}>
    <table {...componentProps.table}>
      <thead {...componentProps.thead}>
        {table.getHeaderGroups().map((headerGroup) => (
          <tr key={headerGroup.id} {...componentProps.trHead?.({ headerGroup })}>
            {headerGroup.headers.map((header) => {
              return (
                // When components rendered in iterator,
                // componentProp is a function that gets relevant iteration context
                <th key={header.id} {...componentProps.th?.({ header })}>
                  {header.isPlaceholder ? null : flexRender(header.column.columnDef.header, header.getContext())}
                </th>
              );
            })}
          </tr>
        ))}
      </thead>
      <tbody {...componentProps.tbody}>
        {virtualRows.map((virtualRow) => {
          const row = table.getRowModel().rows[virtualRow.index];
          return (
            <tr key={virtualRow.index} {...componentProps.trBody?.({ table, row, virtualRow })}>
              {row.getVisibleCells().map((cell) => {
                return (
                  <td key={cell.id} {...componentProps.td?.({ cell, virtualRow })}>
                    {flexRender(cell.column.columnDef.cell, cell.getContext())}
                  </td>
                );
              })}
            </tr>
          );
        })}
      </tbody>
    </table>
  </div>
);

Components

Components useful for building more advanced table features.

We are pretty early on building the components, so there are only a few right now:

<HeaderContextMenu /> - Context menu for column headers, providing sort, show / hide, column pinning
<HeaderSortIndicator /> - Sort indicator icon with sort index (for multi-column sorting)

You can see examples of their use in ./apps/zoos/src/routes/react-table/standard.tsx.

`getColumns` - "Column Type Inference"

Infer columns from data passed to reduce the boilerplate for a generic table.

Current State

No type inference, return columnHelper.accessor() for each column ID

Column Filters

For filtering, a column requires 2 things:

A filterFn (standard for Tanstack table)
A filter component, similar to cell or header (a new field added to columnDef.meta)

The filterFn and filter components are accessed through the filters object. They are organized by column type (e.g. string) and then filter type (e.g. includes, inArray, etc.).

import { type ColumnDef } from "@tanstack/react-table";

import { filters } from "@zoos/react-table";

const data: DataRow[] = [{ ... }];
const columnHelper = createColumnHelper<DataRow>();
const columns: ColumnDef<DataRow> = [
  columnHelper.accessor("name", {
    // Filter function
    filterFn: filters.string.includes.filterFn,
    meta: {
      /*
      Filter component
      - The filter component is *only* the input hooked up to the table column `setCellValue` / `getCellValue`.
      - For filter components which require additional props (e.g. `string.inArray`), you must pass in an array of `options`)
      - You can also pass in custom wrapper / label (e.g. `<div><Label>...</Label><Filter /></div>`)
      */
     filter: (headerContext) => (
            <filters.string.inArray.Filter
              headerContext={headerContext}
              inputProps={{
                // Full control over props passed to input
                // (other than those required to connect to
                // `headerContext.column.setFilterValue()`)
                options: Array.from(
                  headerContext.column.getFacetedUniqueValues().keys(),
                ).sort((a, b) => a.localeCompare(b)),
              }}
            />
          ),
    }
  })
]

There are several filters available for each data type including:

filters.string.includes - Filter for string that include the filter value (performs lowercase on both filter and values)
filters.string.inArray - Filter for rows that include one of the values in the filter array
filters.date.range - Filter for dates within a range
filters.number.range - Filter for numbers within a range

Coming soon

Column Filters

On filter field, pause auto-refreshing filters when user is typing (more control vs. forcing debounce)
filters.stringArray.includesOne - Filter for rows that include one of the values in the filter array
filters.stringArray.includesAll - Filter for rows that include all values in the filter array
