Question

Answer 1

为了完整性，没有 jQuery:

var row = cell.parentNode;
var table_body = row.parentNode;
var neighbors = [];

if (cell.cellIndex > 0) {
    neighbors.push(rows.cells[cell.cellIndex - 1]);
}

if (row.rowIndex > 0) {
    neighbors.push(table_body.rows[row.rowIndex - 1].cells[cell.cellIndex]);
}

if (cell.cellIndex < rows.cells.length - 1) {
    neighbors.push(rows.cells[cell.cellIndex + 1]);
}

if (row.rowIndex < table_body.rows.length - 1) {
    neighbors.push(table_body.rows[row.rowIndex + 1].cells[cell.cellIndex]);
}
