AG Grid使用applyTransaction插入行

问题描述

是否可以在特定索引处而不是在网格末尾插入行?

Is there a way to insert rows at a specific index rather than at the end of the grid?

例如，如果我想从顶部插入10行，该怎么办?还是在中间?

Example would if I want to insert a row 10 rows from the top? Or in the middle?

我确实找到了一种叫做insertItemAtIndex(index, [rows]);

I did find an old ag grid method called insertItemAtIndex(index, [rows]);

，但此方法无效，并表示已弃用.有没有办法用applyTransaction(transaction)做到这一点?

but this isn't working and says it's deprecated. Is there a way to do this with applyTransaction(transaction)?

推荐答案

RowDataTransaction接口具有可选的addIndex属性-

The RowDataTransaction interface has an optional addIndex property -

export interface RowDataTransaction {
    /** deprecated */ addIndex?: number;
    add?: any[];
    remove?: any[];
    update?: any[];
}

尽管已被标记为已弃用，但它对我有用.

Although it is marked deprecated, it is working for me.

用法:this.gridApi.applyTransaction({ add: newItems, addIndex: 2});

它表示将从中插入新行的索引.

我已经尝试过使用示例，并且运行良好.

I have tried playing around on this example from docs and is working fine.
