Didn't find a built in method in JTable, but how about this:
在 JTable 中没有找到内置方法，但是这个怎么样：
private int getColumnByName(JTable table, String name) {
for (int i = 0; i < table.getColumnCount(); ++i)
if (table.getColumnName(i).equals(name))
return i;
return -1;
}
Then you can use the following to set & get cell values :
然后您可以使用以下内容来设置和获取单元格值：
table.setValueAt(value, rowIndex, getColumnByName(table, colName));
table.getValueAt(rowIndex, getColumnByName(table, colName));

you can get a TableColumn from JTable's getColumn method, using the name of the column as the identifier; and get its modelIndex....
您可以从 JTable 的 getColumn 方法中获取一个 TableColumn，使用列的名称作为标识符；并获取其模型索引....
but if your table has sorting; then you need to do translation.
但如果你的桌子有排序；那么你需要做翻译。
I'd recommend implementing what you need in the tableModel for your table.
我建议在 tableModel 中为你的表实现你需要的东西。
