Question Description
When customizing cell content using customLayout, including Text and Image, I would like to have some custom logic when hovering over the Image. Currently, the mouse-enter event for the cell cannot distinguish between specific targets.
For DOM elements in JavaScript, the mouseenter event is triggered only once when the mouse pointer enters (moves over) the element. So is there an event like mouseenter_cell to monitor specified content in custom cells?
Solution
You can bind the mouseenter and mouseleave events to the image dom of the custom layout 'customLayout'.
Code example
You can paste it into the official editor to test:

const VGroup = VTable.VGroup;
const VText = VTable.VText;
const VImage = VTable.VImage;
const VTag = VTable.VTag;
const option = {
container: document.getElementById('container'),
columns: [
{
field: 'bloggerId',
title: 'bloggerId'
},
{
field: 'bloggerName',
title: 'bloggerName',
width: 330,
customLayout: args => {
const { table, row, col, rect } = args;
const { height, width } = rect || table.getCellRect(col, row);
const record = table.getRecordByRowCol(col, row);
// const jsx = jsx;
const container = (
