# Icon column variant

Show Code

# Paragraph column variant

We can use this column variant when we have a bigger text and we need to trim/show this text. Row value for this column variant should be an object with the following properties:

  1. text: Paragraph to trim. Only first three lines from this paragraph would be visible initially. User has to expand to see the full text.
Show Code

# Custom templates

This codeblock shows how to use custom cell function to display HTML content in a cell.

To have custom table headers, we can use 'customHeader' property. This will take in a function with parameters same as customTemplate.




 
 
 


  var columns = [{
    "key": "bookname",
    "text": "Book name",
    "customTemplate": (createElement, props) => {
      return createElement('b', {}, props.text);
    }
  }]

  // Usage examples for createElement:
  // Params should be either (tagName, children) or (tagName, properties, children)
  createElement('div', [createElement('h2', 'Hello')]);
  createElement('div#foo.bar.baz', [createElement('h2', 'Hello')]);
  createElement('div.bar.baz', [createElement('h2', 'Hello')]);
  createElement('div', {className: 'greeting'}, [createElement('h2', 'Hello')]);

# Column text alignment

You can set text alignment in the column by passing the textAlign in column configuration. In the below example, column 'Icon' is center aligned.

Show Code

# Row Actions:

You can easily add an actions column by passing in rowActions prop to the component.

You can also use icons instead of text in buttons. Pass 'iconName' and 'iconLibrary' properties as part of configuration.

Show Code

# Hide columns

To hide certain columns, we can pass the 'hide' property set to true in the column's configuration.

'Role' column hidden in below table.

Show Code

# Column lock

We can lock column using 'lock' in column's configuration.

Show Code

# Column width

We can pass width for every column using 'widthProperties' in column's configuration. Every column has a minimum width of 40px and maximum width of 1000px by default. We can override min/max width for every column using the 'widthProperties' too.

'Name' column has 400px width and 'Role' column has 200px width.

Show Code

# Formatting data

We can format row's data before rendering into a cell by passing 'formatData' in column's configuration.

This option wont work when using this with 'variant' or 'customTemplate' properties in column's configuration.

Show Code

# Table settings

Table settings help with reordering and hide/show of columns. To enable table settings, pass the 'show-settings' prop to the table.

Show Code

# Loading table

We can load a table using the 'loadTable' method available on the table.

Load table

Show Code

# Saving column configuration

For auto saving configuration into localStorage, you can add 'autoSaveSettings' prop to the table.

  <data-table id="data-table-10" label="data table 10" auto-save-settings="true"> 
  </data-table>

Data table exposes couple of method to get and set column configuration.


 
 



  let dataTable = document.querySelector('data-table#config');
  // getColumnConfig helps retrive configuration in JSON format
  let dataTableConfiguration = dataTable.getTableSettings(); 
  // setColumnConfig helps set the configuration. 
  dataTable.setTableSettings(dataTableConfiguration);
