The basics of the Jspreadsheet
In this page we are going to present the basics of Jspreadsheet, how to handle width, height, titles, column types and other basic concepts.
Spreadsheet headers
The developer can define a title for a column. If none is defined, the column name will start with a letter as below.

<div id='spreadsheet'></div>
<script>
jspreadsheet(document.getElementById('spreadsheet'), {
data: [
['Fusca', 1999],
['Camaro', 9999]
],
columns: [
{ width: 100 }
]
});
</script>
</html>
Headers from a CSV file
When creating a Jspreadsheet Spreadsheet from a CSV file, is is possible to consider the first row in the file as the column names using the csvHeaders: true directive, as below:
<html>
<script src="https://jspreadsheet.com/v7/jspreadsheet.js"></script>
<script src="https://jsuites.net/v5/jsuites.js"></script>
<link rel="stylesheet" href="https://jspreadsheet.com/v7/jspreadsheet.css" type="text/css" />
<link rel="stylesheet" href="https://jsuites.net/v5/jsuites.css" type="text/css" />
<div id='spreadsheet'></div>
<script>
jspreadsheet(document.getElementById('spreadsheet'), {
csv: '/jspreadsheet/demo.csv',
csvHeaders: true,
tableOverflow: true,
tableWidth: 600,
});
</script>
</html>
Nested headers
Is it possible to create nested headers using the initialization property nestedHeaders as follow:
<html>
<script src="https://jspreadsheet.com/v7/jspreadsheet.js"></script>
<script src="https://jsuites.net/v5/jsuites.js"></script>
<link rel="stylesheet" href="https://jspreadsheet.com/v7/jspreadsheet.css" type="text/css" />
<link rel="stylesheet" href="https://jsuites.net/v5/jsuites.css" type="text/css" />
<div id='spreadsheet'></div>
<script>
let data = [
['USA', 'Apples', 100],
['USA', 'Bananas', 150],
['USA', 'Oranges', 200],
['UK', 'Apples', 80],
['UK', 'Bananas', 120],
['UK', 'Oranges', 180],
['Canada', 'Apples', 100],
['Canada', 'Bananas', 150],
['Canada', 'Oranges', 50],
]
jspreadsheet(document.getElementById('spreadsheet'), {
data:data,
columns: [
{ type: 'text', title:'Country', width:'300px' },
{ type: 'text', title:'Food', width:'150px' },
{ type: 'text', title:'Stock', width:'100px' },
],
nestedHeaders:[
[
{ title:'Supermarket information', colspan:'3' },
],
[
{ title:'Location', colspan:'1' },
{ title:' Other Information', colspan:'2' }
],
],
});
</script>
</html>
Programmatically updates
The methods setHeader() , getHeader() and getHeaders() are available for the developer to interact programmatically with the spreadsheet headers.
See a working example dealing with headers
Column width
The default column width can be defined using the defaultColWidth initialization property. But, it is also possible to define a specific initial value per column using the property in the column directive as below.
<html>
<script src="https://jspreadsheet.com/v7/jspreadsheet.js"></script>
<script src="https://jsuites.net/v5/jsuites.js"></script>
<link rel="stylesheet" href="https://jspreadsheet.com/v7/jspreadsheet.css" type="text/css" />
<link rel="stylesheet" href="https://jsuites.net/v5/jsuites.css" type="text/css" />
<div id='spreadsheet'></div>
<script>
let data = [
['Fusca', '$ 1999', 58, '1935'],
['Camaro', '$ 9999', 9, '1967']
]
jspreadsheet(document.getElementById('spreadsheet'), {
data: data,
columns: [
{ title:'Model', width:'250px' },
{ title:'Price', width:'80px' },
{ title:'Stock' }, // Will have the default width
{ title:'Date' } // Will have the default width
],
defaultColWidth: '100px'
});
</script>
</html>
Programmatically updates
The methods setWidth(), getWidth() are available to update the column width programatically.
Row height
The inital row height can be defined in the height property include in the rows directive.
<div id="spreadsheet"></div>
<script>
jspreadsheet(document.getElementById('spreadsheet'), {
data: [['Banana'], ['Potato'], ['Apple'], ['Orange'], ['Avocado']],
rows:{ 3: { height:'500px' }},
defaultColWidth: '100px'
});
</script>
Programmatically row height updates
The methods setHeight(), getHeight() are available for the developer to update the row height via javascript.
Column types
In addition to the default input text, Jspreadsheet also brings native column types to your online spreadsheets. This gives you an exact and responsive method to get data into your spreadsheet. You will also find a template to help you create custom column types and rich user interfaces.
Jspreadsheet is integrated with jSuites, which is why you will see certain familiar native columns, such as: text, numeric, hidden, dropdown, autocomplete, checkbox, radio, calendar, image, color, email, and URL.
<script>
jspreadsheet(document.getElementById('spreadsheet'), {
data:data,
columns: [
{ title:'Model', width:300, type:'text'; },
{ title:'Price', width:80, type:'numeric' },
{ title:'Date', width:100, type:'calendar', options: { format:'DD/MM/YYYY' } },
{ title:'Photo', width:150, type:'image' },
{ title:'Condition', width:150, type:'dropdown', source:['New','Used'] },
{ title:'Color', width:80, type:'color' },
{ title:'Available', width:80, type:'checkbox' },
]
});
</script>
Calendar type
When using the calendar column, you can change the behavior behavior of your calendar by sending some extra options as example above. The possible values are:
options : {
// Date format
format:'DD/MM/YYYY',
// Allow keyboard date entry
readonly:0,
// Today is default
today:0,
// Show timepicker
time:0,
// Show the reset button
resetButton:true,
// Placeholder
placeholder:'',
// Translations can be done here
months:['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
weekdays:['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'],
weekdays_short:['S', 'M', 'T', 'W', 'T', 'F', 'S'],
// Value
value:null,
// Events
onclose:null,
onchange:null,
// Fullscreen (this is automatic set for screensize < 800)
fullscreen:false,
};
Dropdown and autocomplete type
There are different ways to work with dropdowns in Jspreadsheet. It is possible to define the parameter source as a simple or key-value array. It is also possible to use the param URL to populate your dropdown from an external JSON format source. In addition to that, it is possible to have conditional values. The values from one dropdown can be conditional to other dropdowns in your table.
You can set the autocomplete dropdown through the initial param autocomplete:true and the multiple picker can be activate by multiple:true property as shown in the following example:
let data = [
['Honda', 1, 'Civic', '4'],
['Peugeot', 3,'1007', '2'],
['Smart', 3,'Cabrio', '4;5'],
];
$('#my').jspreadsheet({
jspreadsheet(document.getElementById('spreadsheet'), {
data:data,
columns: [
{
type:'dropdown',
title:'Region',
source:['South East','South West','North','London'],
width:'200',
},
{
type:'dropdown',
title:'Available in',
multiple:true,
source:[{id:1, name:'Red'},{id:2, name:'Yellow'},{id:3,name:'Blue'}],
width:'200',
},
{
type:'autocomplete',
title:'Region',
url:'values.json',
width:'200',
},
]
});
Custom type
Jspreadsheet makes possible to extend third party javascript plugins to create your custom columns. Basically to use this feature, you should implement some basic methods such as: openEditor, closeEditor, getValue, setValue as following.
let data2 = [
['PHP', '14:00'],
['Javascript', '16:30'],
];
let customColumn = {
// Methods
closeEditor : function(cell, save) {
let value = cell.children[0].value;
cell.innerHTML = value;
return value;
},
openEditor : function(cell) {
// Create input
let element = document.createElement('input');
element.value = cell.innerHTML;
// Update cell
cell.classList.add('editor');
cell.innerHTML = '';
cell.appendChild(element);
$(element).clockpicker({
afterHide:function() {
setTimeout(function() {
// To avoid double call
if (cell.children[0]) {
myTable.closeEditor(cell, true);
}
});
}
});
// Focus on the element
element.focus();
},
getValue : function(cell) {
return cell.innerHTML;
},
setValue : function(cell, value) {
cell.innerHTML = value;
}
}
myTable = jspreadsheet(document.getElementById('custom'), {
data:data2,
columns: [
{ type: 'text', title:'Course Title', width:300 },
{ type: 'text', title:'Time', width:100, editor:customColumn },
]
});
Define a minimum table dimension size.
The follow example will create a data table with a minimum number of ten columns and five rows:
let data3 = [
['Mazda', 2001, 2000],
['Peugeot', 2010, 5000],
['Honda Fit', 2009, 3000],
['Honda CRV', 2010, 6000],
];
jspreadsheet(document.getElementById('minExample'), {
data:data3,
minDimensions:[10,5],
