Possible Usage Scenarios
You might need to set a tooltip for your custom column while creating the table in the worksheet. Aspose.Cells.GridWeb allows you to rename a column’s caption, and you may set a tooltip for the column so users can easily understand what the column is for.
Setting Column Header Tip
A complete example is given below to demonstrate how to change columns' captions and apply tooltip text. After executing the example code, the tooltip text will be displayed when you place the mouse cursor over the specified column’s header.
Sample Code
Here is the sample code of the test.jsp file.
<%@ page language="java" contentType="text/html; charset=UTF-8"
import="com.aspose.gridweb.*" pageEncoding="UTF-8"%>
<!DOCTYPE html>

gridSheet.getCells().get("A1").putValue("Product1");
gridSheet.getCells().get("A2").putValue("Product2");
gridSheet.getCells().get("A3").putValue("Product3");
gridSheet.getCells().get("A4").putValue("Product4");
gridSheet.getCells().get("B1").putValue(100);
gridSheet.getCells().get("B2").putValue(200);
gridSheet.getCells().get("B3").putValue(300);
gridSheet.getCells().get("B4").putValue(400);
// Set the caption of the first two columns.
gridSheet.setColumnCaption(0, "Product Name");
gridSheet.setColumnCaption(1, "Price");
// Set the column width of the first column.
gridSheet.getCells().setColumnWidth(0, 20);
// Set the second column header's tooltip.
gridSheet.setColumnHeaderToolTip(1, "Unit Price of Products");
gridweb.prepareRender();
