reactsupertable v0.1.4

WORK IN PROGRESS

React Programmable Table based on fixed-data-table

Features

• Sortable columns
• Table/column widths in percentages or pixels
• Filtering
• Pagination. Can also extend base paginator to create your own
• Customise columns for width, content and use 'custom renderers' when you need to

Install from NPM

install reactsupertable --save

Basic usage

The table expects a JSON dataset. For example, a dataset that looks like this..

[{
	"id": 0,
	"avatar": "https://s3.amazonaws.com/uifaces/faces/twitter/imammuht/128.jpg",
	"city": "Alyshaborough",
	"email": "Elbert_Feest4@hotmail.com",
	"firstName": "Vaughn",
	"lastName": "D'Amore",
	"street": "Schultz Course",
	"zipCode": "39894",
	"date": "2016-08-24T09:06:37.283Z",
	"bs": "real-time disintermediate e-services",
	"catchPhrase": "Ameliorated national project",
	"companyName": "Glover - Fritsch",
	"words": "voluptatem excepturi vel",
	"sentence": "Soluta qui molestiae aliquid aut inventore voluptas voluptates."
}, {
	"id": 1,
	"avatar": "https://s3.amazonaws.com/uifaces/faces/twitter/iamjdeleon/128.jpg",
	"city": "Lakinton",
	"email": "Davion.West@hotmail.com",
	"firstName": "Leland",
	"lastName": "Ortiz",
	"street": "Joy Ports",
	"zipCode": "13648",
	"date": "2017-04-28T16:55:26.405Z",
	"bs": "out-of-the-box innovate architectures",
	"catchPhrase": "Synergistic actuating success",
	"companyName": "Johnson - Grant",
	"words": "aut et aperiam",
	"sentence": "Dolore qui facere voluptas sed ipsum quis sapiente aut quae."
}, {
	"id": 2,
	"avatar": "https://s3.amazonaws.com/uifaces/faces/twitter/jarsen/128.jpg",
	"city": "Windlerside",
	"email": "Hassie.Ruecker54@gmail.com",
	"firstName": "Kole",
	"lastName": "Gislason",
	"street": "Vida Drive",
	"zipCode": "75116-0721",
	"date": "2017-05-09T22:26:06.088Z",
	"bs": "integrated generate action-items",
	"catchPhrase": "Re-contextualized multi-state customer loyalty",
	"companyName": "Ondricka Inc",
	"words": "ut blanditiis amet",
	"sentence": "Culpa quis et sint."
}]

Let's assume we only want to show id, firstName, lastName, and, city in the table. In our column metadata, we would have:

function getColumnMetaData() {
    return [
        { 'header': 'ID', 'width': '10%', attribute: 'id' },
        { 'header': 'First name', 'width': '20%', attribute: 'firstName' },
        { 'header': 'Last name', 'width': '20%', attribute: 'lastName' },
        { 'header': 'City', 'width': '20%', attribute: 'city'}

    ]
}

And our table Component (with paging) would look like this:

<SuperTable 
            ref={instance => { window.superTable = instance; }}
            columnMeta={ getColumnMetaData() }
            data={data}
            filterPlaceholder='Filter...'
            itemsPerPageText='items per page'
            onCellClickCallback={cellClick}
            onRowClickCallback={rowClick}
            rowsPerPage={10}
            showItemsPerPage={true}
            showPagination={true}
            showText={'Show'}
            showTotalRowCount={true}
            tableHeight={500}
            tableWidth={'100%'}
            totalRowCountText='items found'
            
/>

Important

Although only the attributes that are defined within the column metadata object are shown, the object that is passed back on a cell click or row click event is the entire row. This makes it easy to get data that is not visible 'on screen'. A good use of this is say, an 'id' field that the user doesn't need to know about...but is needed for subsequent operations etc.

Properties

Column Meta Data

Each attribute that you choose to show from your dataset is defined as part of the Column Metadata object. Here's an example:

function getColumnMetaData() {
    return [
        { 'header': 'Special', 'width': '10%', renderer: insertCheckbox, order: 1 },
        { 'header': 'ID', 'width': '10%', attribute: 'id', order: 2 },
        { 'header': 'Email', 'width': '20%', attribute: 'email', order: 3 },
        { 'header': 'City', 'width': '20%', attribute: 'city', order: 4, resize: true },
        { 'header': 'Street', 'width': '20%', attribute: 'street', order: 5 },
        { 'header': 'Zip', 'width': '20%', attribute: 'zipCode', order: 6 }
    ]
}

Notes:

• The width can be in pixels or a percentage.
• Resize allows the user to resize the column width -- but this is not persisted. A later release will provide an option to persist.
• To 'insert' a column -- as shown in the first attribute -- do not supply an attribute. But, you must provide a custom rendereder.

Custom Renderers and Inserting New Attributes

Each attribute is simply displayed as text. However, chances are that you want to show your data in a different format. Consider timestamps. You probably would not show a raw timestamp to a user, but would format it . This is what a customer renderer allows you to do. Here's how you would do that for a timestamp -- along with inserting a checkbox in the first column. Condider this metadata:

function getColumnMetaData() {
    return [
        { 'header': 'Special', 'width': '10%', renderer: insertCheckbox },
        { 'header': 'Timestamp', 'width': '20%', attribute: 'timestamp', renderer: dateRenderer  }
    ]
}

Renderer insertCheckbox

Is simply a function that will be called with the following parmameters:

• rowindex --> The index of the current row
• data --> An object that represents the current row. To get the raw data for this attribute, use datacolumnName Not used when inserting a column.
• columnName --> The column name. In this case, 'Special'

function insertCheckbox(rowIndex, data, columnName) {
    // Just return a checkbox type
    return <input type='checkbox' />

}

Renderer dateRenderer

dateRenderer(rowIndex, data, columnKey) {
    return {new Date(data[columnKey]).getTime()}
}

Event Handling

The table can call back on cell click events, and row click events. The row click event receives a row object and the cell click event receives the raw data for this cell.

This row object contains the entire row, not just the attributes that are displayed. To retrieve a single attribute from this row, simply use row.attribute for a row click. For example:

<SuperTable 
            . . . 
            onCellClickCallback={cellClick}
            onRowClickCallback={rowClick}
            . . .
/>            

// Show the attribute name and its value for this cell
function cellClick(rowIndex, column, cell) {
    alert('Cell clicked! attribute name : ' + column + ' Cell is: ' + cell );
}

// Show the id attribute for this row
function rowClick(row) {
    alert('Row clicked! Id is: ' + row.id)
}

Refreshing Data

In order to tell SuperTable to refresh its data store, you must explicilty call the refresh method. This is done in the following way. First, define a 'ref' in the table to get visibility to SuperTable's methods.

<SuperTable 
            . . .
            ref={instance => { window.superTable = instance; }}
            . . .

I've attached it to the global Window object here.. but is usually 'this' when using from a React Component etc. When you decide that you need to update the data store...

function refreshData( data ) {
 
    if (undefined !== window.superTable) {
        window.superTable.refresh(data);
    }
}

Here, refreshData is called with what is the updated dataset. SuperTable's refresh method is invoked and the table repaints.

This does it for version 1.0

Thanks...Much more to come
