You have all you need in handler params
您拥有处理程序参数所需的一切
handler: function(grid, rowIndex, colIndex) {
var row = grid.getStore().getAt(rowIndex);
console.log(row);
}
The code above will give you the row, so you just need to select desired cell.
上面的代码会给你行，所以你只需要选择所需的单元格。
If you enforce selection before clicking actioncolumn you can also use code below. But be aware by default clicking on actioncolumn doesn't fire selection, so while clicking actioncolumn an entirely different row can be selected or even no column can be selected at all.
如果您在单击 actioncolumn 之前强制选择，您还可以使用下面的代码。但是请注意，默认情况下单击 actioncolumn 不会触发选择，因此在单击 actioncolumn 时可以选择完全不同的行，甚至可以根本不选择任何列。
grid.getSelectionModel().getSelection()
