Format raw data into ease to handle table data.

:warning: It's core version of tabless, ready to use implementations of tabless in e.g. React, Vue will be avaiable soon.

Installing

$ npm install @savuelo/tabless-core

import Tabless from '@savuelo/tabless-core';

OR

<script src="/bundle/tabless.js"></script>

Running example

1: Install dependecies

$ npm install

2: Start server

$ npm run dev

3: Navigate to /example/index.html in your browser

Usage

At first You should create object with configuration of columns in table.

const columns = [ 
  {
    columnName: 'Name:', // Display name of column
    columnIndex: 'name', // index/property of object with data
  },
  {
    columnName: 'Lastname:',
    columnIndex: 'lastname',

    /*
      Format function what will be used to format data in column
      In this case all of the data in this column will be uppercased
    */
    columnFormat: (value) => {
      return value.toUpperCase();
    }
  }
];

Available column config options

Required:

string columnIndex : Index or property of data object.

Optional:

string columnName : Name of the column (header name).
function columnFormat : Function used to format data in the column.
string columnClassName : Class name of the column.
string | number columnId : User defined id of column, should be unique.

Example data

Note that empty objects will be skipped during generation of output Table.

const data = [
  {
    name: 'Hubert', 
    lastname: 'Dziuda', 
  },
  {
    name: 'John',
    lastname: 'snow',
  },
  {
    name: 'John', 
    lastname: 'Smith', 
  },
  {
    name: 'Mark',
    lastname: 'Steward', 
  }
];

Create config object

Providing config object is optional.

const config = {
  addOrdinalNumber: true, //Creates column with ordinal number
}

Avaiable config options

bolean addOrdinalNumber : default false, add optional column with ordinary numbery.
string ordinalHeader : default 'No.', header of ordinary number column.
string ordinalColumnClassName : default 'ordinal', class name of ordinal number column.
string orderBy : default 'undefined', index/property of data object used in sorting. If not defined or property is not valid table won't be sorted.* boolean descending : default false, set to true if you want to sort your table descending. Works only when orderBy config is set.
boolean headerless : default false, set to true if you want to generate table array without header row (you still have to pass columnConfig!) Make sure you adjust implementation of the renderWay method.

:warning: * when sorting make sure that all of the data in column in table represents the same type.

Create instace of Tabless

const tabless = new Tabless(columns, data, config);

Configuring existing Tabless instance

To change configuration of existing Tabless instance call setConfig method and pass config object. It will overwrite config options and effect every of future renders.

tabless.setConfig({
  orderBy: 'age',
  descending: true,
})

Adding new column(s)

To add a new column to the existing table use addColumn method.

tabless.addColumn({
  columnName: 'Age:',
  columnIndex: 'age',
  columnId: 'ageColumn',
});

//OR

tabless.addColumns([{
  columnName: 'Lastname:',
  columnIndex: 'lastname',
  columnId: 'lastenameColumn',
},{
  columnName: 'Age:',
  columnIndex: 'age',
  columnId: 'ageColumn',
}]);

Removing column(s)

You can remove columny by its columnId or by number in array (counting from 0, from left to right excluding ordinary column, in output table).

tabless.removeColumnsById('ageColumn');
//OR
tabless.removeColumnsById(['ageColumn', 'nameColumn']);
//OR 
tabless.removeColumnsByIndex(2);
//OR
tabless.removeColumnsByIndex([0,1,2]);

Adding new row(s)

To create new rows in existing Tabless instance use addRows method. It accepts 2 params: Object or array of objects with data of the new rows, and boolean what decides about putting new rows to the start or end of the table. Note that if you are using sorting data in Tabless new row will be sorted as normal row, even if you pass param that puts it on the start of the table.
After adding new row you should re-render the table. It may affect absolute id of other rows.

// row to the table
tabless.addRow({
  name: 'Ron',
  lastname: 'Jenkins',
  age: 22,
}, true); //second parameter is true, so the new row will be added at the beginning of the table. 

//OR

tabless.addRows([{
  name: 'Ron',
  lastname: 'Jenkins',
  age: 22,
},{
  name: 'Lucas',
  lastname: 'Murphy',
  age: 33,
}]);

Removing row(s)

To remove row from array pass row's absolute id into removeRows method. Be careful! This action may afftect absolute ids of other rows. You should re-render table to obtain actual absolute ids.

tabless.removeRows(2);

To remove multiple rows at once just pass an array as param.

tabless.removeRows([0, 1, 2, 3]);

Replacing data object

//Replace all the existing data with new.
tabless.replaceData(newData);

Implement tabless in you environment

:warning: It's core version of tabless, ready to use implementations of tabless in e.g. React, Vue will be avaiable soon.

Override renderWay function in your Tabless instance with your implementation.

renderWay recives as param array with of TableRow objects (which store row id and array of cells in this row). Cells are object that store formated data ready to be displayed in table and their className (column dependent).

First element of that array is headers row.

Table Row Object:

number absoluteId : stores absoluteId of row (absolute id is index of that row in source data Array, for headers row it have value of '-1').
array cells : array of Cells object.

Cell Object:

string value : value of cell.
string className : cell class name.

renderWay should return ready to display table of any desired type.

Example of renderWay:

Code below is meant to work in browser environment.

:warning: Code below is just simplified example! It's not optimised and do not follow rules of good coding.

tabless.renderWay = (data) => {
  const tableElement = document.createElement('table');
  const tableHead = document.createElement('thead');
  const tableBody = document.createElement('tbody');

  data.forEach(({cells}, i)=>{
    let elementType = 'td';

    if(i === 0){ // render first object as table header
      elementType = 'th';
    }

    const rowElement = document.createElement('tr');

    cells.forEach(({value, className})=>{
      const cell = document.createElement(elementType); //th or td

      cell.innerHTML = value;

      if(className){
        cell.classList.add(className);
      }
      rowElement.append(cell);
    });

    if(i === 0){ //put header into thead element 
      tableHead.append(rowElement);
    }else{
      tableBody.append(rowElement);
    }
  })

  tableElement.append(tableHead);
  tableElement.append(tableBody);

  return tableElement;
}

To execute code, call render method of your Tabless instance

document.getElementById('id-of-element').append(tabless.render());

Other methods:

//Replace all columns with new ones.
tabless.replaceColumns(columns);

//Return unformated data and columns list with config.
tabless.getColumns();
tabless.getData();
