[Bug] 虚拟表头下的单元格编辑问题

列头或者行头存在虚拟表头时，下面的单元格存在两个问题：
调出编辑框时，input 框取不到原始值
结束编辑状态时，单元格不显示新值（只有再次调出编辑框时才会显示新值）
let tableInstance;
const input_editor = new VTable_editors.InputEditor();
VTable.register.editor('input-editor', input_editor);
fetch('https://lf9-dp-fe-cms-tos.byteorg.com/obj/bit-cloud/VTable/North_American_Superstore_Pivot_Chart_data.json')
  .then(res => res.json())
  .then(data => {
