Steps to Export HTML Table Data to Excel using JavaScript
HTML Table Data:
JavaScript Code:
1. HTML Table Data
Export HTML data in Excel, even before we have to load some data into an HTML table. So here we have to make fetch employee table data and load it in an HTML table with table columns like name, address, gender, designation, and age. Here we have created an HTML table with id employee_data. So this id we will use for fetch this HTML table data in JavaScript code. Under this HTML code, we have made one button tag with id export_button, so when use has clicked on this button, then HTML table data will be download in Excel file format without refresh of a web page using JavaScript.
2. JavaScript Code
In this tutorial, we have to use SheetJS JavaScript Library to export HTML table data to Excel using JavaScript. So first we have to include the following SheetJS library link at the header of this HTML web page.
In the JavaScript code part, first we have created the html_table_to_excel(type) function. This function has used sheetJS library function and convert or write HTML table data to excel format and download it in a browser without refreshing the web page.
Once a function is ready then we have to call html_table_to_excel(type) function on the button click event, so for the trigger button click event, we have to use the addEventListener method. So when a user has clicked the button the html_table_to_excel(type) function is called with the xlsx file type. Then it will download the HTML table data in .xlsx format Excel file in the browser without having to refresh a Web page on the client-side.
This property is used to define how an element should display. Every HTML element has a default display value depending on what type of element it is. The default display value for most elements is block or inline.
display properties use below –
inline
block
flex
inline-block
inline-flex
inline-table
list-item
run-in
table
table-row-group
table-caption
table-column-group
table-header-group
table-footer-group
table-cell
table-column
table-row none
Display–
inline – When we set this value, the element does not start on a new line and only takes up as much width as necessary (we can’t set width/height it won’t work)
block – When we set this value, element always starts on a new line and takes up the full width available (we can set width/height)
inline-block – It is combination of inline and block value. It doesn’t start on new line but we can set width and height.
none – The element will not be displayed at all (has no effect on layout)
flex – Displays an element as a block-level flex container.
inline-flex – Displays an element as an inline-level flex container.
inline-table – The element is displayed as an inline-level table
run-in – Displays an element as either block or inline, depending on context
table – It works like a element
table-caption – It works like a element
table-header-group – It works like a element
table-footer-group – It works like a element
table-row-group – It works like a element
table-cell – It works like a element
table-row – It works like a element
list-item – It works like a element
justify-content–
This property is used to align the flexible container’s items when the items do not use all available space on the main-axis (horizontally). We can set this property to flex-start (default), flex-end, center, space-between, space-around.
Ex: –
div { justify-content: center; }
flex-start – This is used to position the item at the beginning of the container
flex-end – This is used to position the item at the end of the container
center – This is used to position the item at the center of the container
space-between – This is used to position the item with space between the lines
space-around – This is used to position the item with space before, between, and after the lines
align-items–
This property is used to specify the default alignment for items inside the container. This property can be override using align-self property for each item. We can set this property to stretch (default), center, flex-start, flex-end, baseline.
Ex: –
div { align-items: center; }
stretch – This is used to stretch the item to fit the container
center – This is used to position the item at the center of the container
flex-start – This is used to position the item at the beginning of the container
flex-end – This is used to position the item at the end of the container
baseline – This is used to position the item at the baseline of the container
align-content–
This property is used to modify the behavior of the flex-wrap property. It is similar to align-items, but instead of aligning flex items, it aligns flex lines. There must be multiple lines of items for this property to have any effect. We can set this property to stretch (default), center,flex-start, flex-end, space-between, space-around.
Ex: –
div { align-content: center; }
stretch – Lines stretch to take up the remaining space
center – Lines are packed toward the center of the flex container
flex-start – Lines are packed toward the start of the flex container
flex-end – Lines are packed toward the end of the flex container
space-between – Lines are evenly distributed in the flex container
space-around – Lines are evenly distributed in the flex container, with half-size spaces on either end
order–
This property is used to specify the order of a flexible item relative to the rest of the flexible items inside the same container. If the element is not a flexible item, the order property has no effect. We can set this property to number (default 0).
Ex: –
div {order: 1}
align-self–
This property is used to specify the alignment for the selected item inside the flexible container. The align-self property overrides the flexible container’s align-items property. We can set this property to auto (default), stretch, center, flex-start, flex-end, baseline.
Ex: –
div {align-self: center;}
auto – The element inherits its parent container’s align-items property, or “stretch” if it has no parent container
stretch – This is used to position the element to fit the container
center – This is used to position the element at the center of the container
flex-start – This is used to position the element at the beginning of the container
flex-end – This is used to position the element at the end of the container
baseline – This is used to position the element at the baseline of the container
This property is used to define how an element should display. Every HTML element has a default display value depending on what type of element it is. The default display value for most elements is block or inline.
inline
table-row-group
block
table-caption
flex
table-column-group
inline-block
table-header-group
inline-flex
table-footer-group
inline-table
table-cell
list-item
table-column
run-in
table-row
table
none
p { display: inline; }
Block-level Elements–
A Block-level element always starts on a new line and takes up the full width available.
Ex: –
<div>
<h1>
<p>
Inline Elements–
An inline element does not start on a new line and only takes up as much width as necessary.
Ex: –
<span>
<a>
<img>
Display–
•inline – When we set this value, the element does not start on a new line and only takes up as much width as necessary (we can’t set width/height it won’t work)
•block – When we set this value, element always starts on a new line and takes up the full width available (we can set width/height)
•inline-block – It is combination of inline and block value. It doesn’t start on new line but we can set width and height.
•none – The element will not be displayed at all (has no effect on layout)
•flex – Displays an element as a block-level flex container.
•inline-flex – Displays an element as an inline-level flex container.
•inline-table – The element is displayed as an inline-level table
•run-in – Displays an element as either block or inline, depending on context
This property is used to set whether or not to display borders and background on empty cells in a table. It will work only if the border-collapse is set to separate. We can set this property to show (default) or hide.
Ex:-
table { table-layout: fixed; }
How to set Table width and Height?
We use width and height property to set table width and height.
We can also set table heading (th) width and height.
table { width: 100% ;}
th { height: 10px; }
How to set Table Padding?
This property is used to control the space between the border and the content in a table, this is used on <td> and <th> elements.
