react-native-data-table

A React Native data table written purely in JSX with React and RealmJS DB (until refactor).

Installation

npm install --save react-native-data-table

Usage

react-native-data-table provides a number of components for constructing a table through composition.

DataTable

This component acts as a wrapper around the React Native ListView component. All the other components in this library should be used in the renderRow and renderHeader.

Prop Name	Type	Description
ListView Props	-	Will pass through any extra props to ListView
listViewStyle	style	Will override styling of the ListView within the DataTable
style	style	Style of the DataTable container (View)
dataSource	object (required)	See ListView
renderRow	func (required)	See RenderRow. Function can return anything, but the Cell components in this library are to make it easy for constructing a table
renderHeader	func	Provide this function with appropriate return to make a table header
refCallback	func	CallBack for utilising reference of the inner TextInput

Cell

Renders a Cell that supports having a string as children, or any component.

<Cell>Hello 1234</Cell>

Prop Name	Type	Description
textStyle	style	Will override styling of the Text label within the button
style	style	Will override styling of the TouchableHighlight enclosing the button
width	number	Gives width relative to other cells in the same container (via flexbox)
children	any	Content of the cell; string, number or any component
numberOfLines	number	Defines the number of lines in the cell that text should use

CheckableCell

Renders a CheckableCell that renders either renderIsChecked or renderIsNotChecked when isChecked is true or false respectively. Whole cell returned is pressable. Callback should affect state of Parent in some way that keeps the state of parent in sync with state of the CheckableCell. Kept separate to maintain responsiveness of the cell.

Prop Name	Type	Description
isChecked	boolean	Used to set the initial state of the cell when the component mounts or rerenders (e.g. table sort order change)
isDisabled	boolean	Will cause renderDisabled to be shown in the cell
style	style	Style of the CheckableCell (View props)
width	number	Gives width relative to other cells in the same container (via flexbox)
onPress	func	CallBack Function for handling user pressing CheckableCell
renderIsChecked	object	Object is rendered as child in CheckableCell if checked
renderIsNotChecked	object	Object is rendered as child in CheckableCell if not checked
renderDisabled	object	Object is rendered as child in CheckableCell if isDisabled is true

EditableCell

Renders a cell with an editable text input. Has own state for managing TextInput content and has onEndEditing callback for utilising user input.

Prop Name	Type	Description
TextInput Props	-	Will pass through any extra props to TextInput
textStyle	style	Will override styling of the TextInput within the button
style	style	Style of the EditableCell (View props)
width	number	Gives width relative to other cells in the same container (via flexbox)
onEndEditing	func	Will be called with 2 params: target and the newValue on end of editing. This function should run code to persist the change to local storage
target	object	Data object of the row/record being edited
value	string or number	Provides initial value. Will change what cell shows if prop changes
refCallback	func	CallBack for utilising reference of the inner TextInput

Header

A container for header cells, should be the outermost component returned in the renderHeader function given to the DataTable renderHeader prop.

HeaderCell

Renders a headerCell that supports being a plain View with Text or being a TouchableOpacity (with callback). In the latter case sort arrows will be rendered and controlled with isSelected and isAscending props. This could also be thought of as "column headers", as that is what this component sets out to ultimately achieve.

Prop Name	Type	Description
TouchableOpacity Props	-	Will pass through any extra props to TouchableOpacity
textStyle	style	Will override styling of the Text label within the HeaderCell
style	style	Will override styling of the TouchableHighlight enclosing the button
width	number	Gives width relative to other cells in the same container (via flexbox)
onPress	func	CallBack Function for handling user pressing headerCell. Should change some parent state that affects the following 2 props
isSelected	Boolean	When false up+down sort arrows renderHeader, otherwise as below
isAscending	Boolean	Sort arrow up if true, down if false.

Row

A container to be used in renderRow function in DataTable renderRow Prop. Has internal state that knows whether the row is expanded or not. Toggled on press. Will only render an expansion if provided.

renderRow(record) {
  <Row>
    <Cell>record.code</Cell>
    <Cell>record.name</Cell>
    <EditableCell
      value={record.quantity}
    />
  </Row>
}

Prop Name	Type	Description
style	style	Will override styling of the TouchableHighlight enclosing the button
children	any	Content of the Row; construct with Cell, EditableCell, etc.
onPress	func	CallBack for doing anything on the press of the row. Also toggles expansion
isExpanded	boolean	If true, the expansion defined renderExpansion will be shown below this row, moving other rows down.
renderExpansion	func	A function that should return an Expansion component with custom content

Expansion

Literally just a wrapper for View. To be used in the Row prop 'renderExpansion'. Made basically just for consistent semantics.

Prop Name	Type	Description
View Props	-	Will pass through any extra props to View

TableButton

Like expansion, this is essentially just a wrapper around TouchableOpacity with a default flex value of 1. Which I believe became redundant at some point in RN development.
