[Feature] 通过column.field控制冻结列

[fourteendp]

What problem does this feature solve?

方便外部控制冻结列

What does the proposed API look like?

以下个人业务中实现

  frozenColConfig?: {
    leftField: string;
    rightField: string;
  };

export const columnsToList = (
  columns: VTableOptions['columns'],
  parentField?: string,
): VTableOptions['columns'] => {
  const result: VTableOptions['columns'] = [];
  cloneDeep(columns!).forEach((column) => {
    if (column.columns && column.columns.length) {
      result.push(
        ...(columnsToList(
          column.columns,
          parentField ? `${parentField}.${column.field}` : column.field,
        ) ?? []),
      );
    } else {
      if (parentField) {
        column.field = `${parentField}.${column.field}`;
      }
      result.push(column);
    }
  });
  return result;
};

export const getFrozenColCount = (
  options: VTableOptions,
  columns: VTableOptions['columns'],
  frozenColCount = 0,
  rightFrozenColCount = 0,
): {
  frozenColCount: number;
  rightFrozenColCount: number;
} => {
  const { leftField = 'isCheck', rightField = '' } = options.frozenColConfig ?? {};
  const columnsList = columnsToList(columns ?? []);

  const leftFrozenColCount = columnsList!.findIndex((column) => column.field === leftField) + 1;
  const _rightFrozenColCount =
    columnsList!.reverse().findIndex((column) => column.field === rightField) + 1;
  if (leftFrozenColCount !== -1) {
    frozenColCount += leftFrozenColCount;
  }
  if (rightFrozenColCount !== -1) {
    rightFrozenColCount += _rightFrozenColCount;
  }

  return {
    frozenColCount,
    rightFrozenColCount,
  };
};

收到。可能最近没有时间安排这个需求。
可以暂时使用frozenColCount来实现 。 调整好columns中的顺序 需要冻结的放到前面
