API Reference


BodyRow represents the model of a <tr> element in <tbody>.


id: string

An id that uniquely identifies the row.


Do not use id to identify a data item because id may also represent the structure of sub-rows. Use dataId instead.

id may be delimited by > to represent the id of parent rows if they exist.

attrs: () => Readable<BodyRowAttributes>

A Readable store with attributes to apply onto the <tr> element.

props: () => Readable<BodyRowProps>

A Readable store with additional properties derived from plugin view model extensions.

cells: BodyCell[]

An array of BodyCells to iterate over and apply onto <td> elements.

cells only includes the cells of visible columns.

cellForId: Record<string, BodyCell>

A record of column ids to BodyCells.

cellForId also includes hidden cells and is useful when you need to reference to a specific cell.

depth: number

The current depth of the row.

Starts at 0 for top-level rows and increases by one for each level of sub-row.

parentRow?: BodyRow

The parent row of the current row if it exists.

undefined if this row is not a sub-row.

subRows?: BodyRow[]

The sub rows of the current row if it exists. undefined if this row has no sub-rows.

By default, the following plugins can define sub-rows:

isData: () => boolean

Returns true if the body row is an instance of DataBodyRow.

isDisplay: () => boolean

Returns true if the body row is an instance of DisplayBodyRow.



DisplayBodyRows represent rows which are not backed by any data item. These rows are usually the result of row aggregation with addGroupBy.


DataBodyRows represent rows which are backed by a data item from the data source.

dataId: string

The original id of the data item from the data source.

This can be configured during createViewModel.

original: Item

The original data item from the data source which backs this data row.

One common pattern is to define additional properties on the data items of the data source and access them via row.original.

  const data = writable([
      name: "Ada Lovelace",
      age: 28,
      disabled: true,
      name: "Ken Thompson",
      age: 64,
      disabled: false,
{#each $rows as row (row.id)}
  <Subscribe attrs={row.attrs()} let:attrs>
    <tr {...attrs} class:disabled={row.original.disabled}>
