How to rename ‘Checkbox’ column in Salesforce Lightning ‘datatable’ component?

Hello Prachi,

You can change the name of the checkbox in lightning through CSS. The CSS code is provided below:

.THIS .slds-th__action_form span {

display: none;

}

.THIS .slds-th__action_form:after{

content: ‘AAA’; //Change to text that you want

}

But then you will have to adjust/increase the width of the column to fit your text.
