我在其他问题中看到，它可能来自表名。它们之间是有空格的，但我改了之后，还是不起作用 您正在执行命令：
create_income_table income(
_id INTEGER PRIMARY KEY AUTOINCREMENT,
income_amount TEXT NOT NULL,
income_payer TEXT NOT NULL,
income_date TEXT NOT NULL,
income_category TEXT NOT NULL,
income_payments TEXT NOT NULL
);
创建收入表创建表CREATE TABLE income(
_id INTEGER PRIMARY KEY AUTOINCREMENT,
income_amount TEXT NOT NULL,
income_payer TEXT NOT NULL,
income_date TEXT NOT NULL,
income_category TEXT NOT NULL,
income_payments TEXT NOT NULL
);
例外情况清楚地显示在这一行中
