🖋 Description

When scrolling the spreadsheet, the return of getMeta function is confusing after extending class MergedCell . It returns data or null .

⌨️ Code Snapshots

export const getTempMergedCell = (
  allVisibleCells: DataCell[],
  sheet?: SpreadSheet,
  cellsInfos: MergedCellInfo[] = [],
): TempMergedCell => {
  const { cellsMeta, cells, invisibleCellInfo } = getVisibleInfo(
    cellsInfos,
    allVisibleCells,
  );
  let viewMeta: ViewMeta | Node | undefined = cellsMeta;
  let mergedAllCells: DataCell[] = cells;
  // some cells are invisible and some cells are visible
  const isPartiallyVisible =
    invisibleCellInfo?.length > 0 &&
    invisibleCellInfo.length < cellsInfos.length;

  // 当 MergedCell 只有部分在可视区域时，在此获取 MergedCell 不在可视区域内的 cells
  if (isPartiallyVisible) {
    const { cells: invisibleCells, cellsMeta: invisibleMeta } =
      getInvisibleInfo(invisibleCellInfo, sheet!);

    viewMeta = viewMeta || invisibleMeta;
    mergedAllCells = cells.concat(invisibleCells); // this is the boob which will explode anytime
  }

  if (!isEmpty(cells) && !viewMeta) {
    // 如果没有指定合并后的文本绘制的位置，默认画在选择的第一个单元格内
    viewMeta = mergedAllCells[0]?.getMeta() as ViewMeta;
  }

  return {
    cells: mergedAllCells,
    viewMeta: viewMeta as ViewMeta,
  };
};

When scolling the spreadsheet， invisibleCells may be any position includes top, bottom, left , right . But here , Simplely add it to the tail. So the viewMeta will be data or null .

mergedAllCells should be sorted by colIndex and rowIndex .
