AG Grid inserting rows with applyTransaction

问题

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

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

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

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

回答1:

The RowDataTransaction interface has an optional addIndex property -

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

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

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

It denotes the index from which new rows will be inserted.

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