Quarterly Update - Summer 2022

By admin·2022-09-01

Over the summer, we continued our work on preparing for our official release, focusing mainly on adding new functionalities and documenting them thoroughly, together with enhancements to existing features.

Summary

We have implemented a few new functionalities, including:

row selection is now available 🎉
column rendering pipeline
group columns are now sortable 🔃

And we have updated some of the existing features:

group columns inherit styles and configuration
column hiding when grouping
group columns can be bound to a field
using the column valueGetter in sorting

Coming soon

We started working on column and context menus. We will first release fully customizable column menus to show/hide columns and to easily perform other operations on columns. This will be followed by context menus where you will be able to define your own custom actions on rows/cells in the table.

Don't worry, the menus will be fully customizable, the menu items are fully replaceable with whatever you need, or you will be able to swap our menu component with a custom one of your own.

New Features

Here's what we shipped over the summer:

Row Selection

Row selection can be single or multiple, with or without a checkbox, with or without grouping and for a lazy or non-lazy DataSource - 😅 that was a long enumeration, but seriously, we think we got something great out there.

You can specify the selection via the rowSelection (controlled) or defaultRowSelection (uncontrolled) props, and listen to changes via the onRowSelectionChange callback prop.

Multi row checkbox selection with grouping

Example shows how you can use multiple row selection with a predefined controlled value.
Go ahead and select some groups/rows and see the selection value adjust.
Example also shows how you can use the InfiniteTableApi to retrieve the actual ids of the selected rows.

Single vs multiple selection, grouped or ungrouped data, checkbox selection, lazy selection - read about all the possible combinations you can use to fit your needs.

Column Rendering Pipeline

The rendering pipeline for columns is a series of functions defined on the column that are called while rendering.

Note

All the functions that have the word render in their name will be called with an object that has a renderBag property, which contains values that will be rendered.

The default columns.render function (the last one in the pipeline) ends up rendering a few things:

a value - generally comes from the field the column is bound to
a groupIcon - for group columns
a selectionCheckBox - for columns that have columns.renderSelectionCheckBox defined (combined with row selection)

When the rendering process starts for a column cell, all the above end up in the renderBag object.

For example:

const column: InfiniteTableColumn<T> = {
  valueGetter: () => 'world',
  renderValue: ({ value, renderBag, rowInfo }) => {
    // at this stage, `value` is 'world' and `renderBag.value` has the same value, 'world'
    return <b>{value}</b>;
  },

  render: ({ value, renderBag, rowInfo }) => {
    // at this stage `value` is 'world'
    // but `renderBag.value` is <b>world</b>, as this was the value returned by `renderValue`
    return <div>Hello {renderBag.value}!</div>;
  },
};

Read about how using the rendering pipeline helps your write less code.

Here is the full list of the functions in the rendering pipeline, in order of invocation:

1.columns.valueGetter - doesn't have access to renderBag 2.columns.valueFormatter - doesn't have access to renderBag 3.columns.renderGroupIcon - can use all properties in renderBag 4.columns.renderSelectionCheckBox - can use all properties in renderBag 5.columns.renderValue - can use all properties in renderBag 6.columns.renderGroupValue - can use all properties in renderBag 7.columns.renderLeafValue - can use all properties in renderBag 8.columns.render - can use all properties in renderBag

Additionally, the columns.components.ColumnCell custom component has access to the renderBag via useInfiniteColumnCell

Sortable Group Columns

When groupRenderStrategy="single-column" is used, the group column is sortable by default if all the columns that are involved in grouping are sortable.

Sorting the group column makes the sortInfo have a value that looks like this:

const sortInfo = [{ field: ['stack', 'age'], dir: 1, id: 'group-by' }];

When groupRenderStrategy="multi-column", each group column is sortable by default if the column with the corresponding field is sortable.

Hint

In both single and multi group column render strategy, you can use the columns.sortable property to override the default behavior.

Updated Features

Here’s a list of Infinite Table functionalities that we enhanced in the last month:

Enhanced Group Columns

Group columns now inherit configuration from the columns bound to the field they are grouped by - if such columns exist.

Group column inherits style from related column

In this example, the group column inherits the styling of the country column, because the country field is used for grouping.

Note

The generated group column(s) - can be one for all groups or one for each group - will inherit the style/className/renderers from the columns corresponding to the group fields themselves (if those columns exist).

Additionally, there are other ways to override those inherited configurations, in order to configure the group columns:

use groupBy.column to specify how each grouping column should look for the respective field (in case of groupRenderStrateg="multi-column")
use groupColumn prop
- can be used as an object - ideal for when you have simple requirements and when groupRenderStrateg="single-column"
- as a function that returns a column configuration - can be used like this in either single or multiple group render strategy

Column Hiding when Grouping

When grouping is enabled, you can choose to hide some columns. Here are the two main ways to do this:

use hideColumnWhenGrouped - this will make columns bound to the group fields be hidden when grouping is active
use columns.defaultHiddenWhenGroupedBy (also available on the column types, as columnTypes.defaultHiddenWhenGroupedBy) - this is a column-level property, so you have more fine-grained control over what is hidden and when.

Valid values for columns.defaultHiddenWhenGroupedBy are:

"*" - when any grouping is active, hide the column that specifies this property
true - when the field this column is bound to is used in grouping, hides this column
keyof DATA_TYPE - specify an exact field that, when grouped by, makes this column be hidden
{[k in keyof DATA_TYPE]: true} - an object that can specify more fields. When there is grouping by any of those fields, the current column gets hidden.

Hide columns when grouping

In this example, the column bound to firstName field is set to hide when any grouping is active, since the group column is anyways found to the firstName field.

In addition, hideColumnWhenGrouped is set to true, so the stack and preferredLanguage columns are also hidden, since they are grouped by.

Group Columns Bound to a Field

Group columns can now be bound to a field, by leveraging the (obviously ...) columns.field property. This will make the group column render the value of that field for non-group rows.

Group columns with field

In addition, you can now use columns.renderGroupValue and columns.renderLeafValue for configuring the rendered value for grouped vs non-grouped rows.

Column valueGetter in Sorting

Columns allow you to define a valueGetter to change the value they are rendering (e.g. useful when the DataSet has nested objects).

Previously, this value returned by columns.valueGetter was not used when sorting the table. With the latest update, the value returned by valueGetter is correctly used when sorting the grid locally.
