我如何对 Excel 中的列索引执行数学运算

Question

我想做一些数学运算，例如：

  builder.WithOrigins("http://example.com")
                           .WithHeaders(HeaderNames.ContentType) // Add your allowed headers here
                           .WithMethods("PUT", "DELETE", "GET", "OPTIONS");

我该怎么做？

使用 #[allow(non_snake_case)] pub fn pixelsWhatever( &self, arg0: &RenderTargetRect, arg1: &str, arg2: i32, arg3: &AffineTransform, ) -> Result<Vec<i8>, jni::errors::Error> { use jni_boilerplate_helper::{ConvertJValueToRust, ConvertRustToJValue, JavaSignatureFor}; #[cfg(debug_assertions)] jni_boilerplate_helper::panic_if_bad_sigs(&[ <&RenderTargetRect as JavaSignatureFor>::signature_for(), <&str as JavaSignatureFor>::signature_for(), <i32 as JavaSignatureFor>::signature_for(), <&AffineTransform as JavaSignatureFor>::signature_for(), <Vec<i8> as JavaSignatureFor>::signature_for(), ]); let tmp0 = ConvertRustToJValue::into_temporary(arg0, self.jni_env)?; let tmp1 = ConvertRustToJValue::into_temporary(arg1, self.jni_env)?; let tmp2 = ConvertRustToJValue::into_temporary(arg2, self.jni_env)?; let tmp3 = ConvertRustToJValue::into_temporary(arg3, self.jni_env)?; let sig = String::from("(") + &<&RenderTargetRect as JavaSignatureFor>::signature_for() + &<&str as JavaSignatureFor>::signature_for() + &<i32 as JavaSignatureFor>::signature_for() + &<&AffineTransform as JavaSignatureFor>::signature_for() + ")" + &<Vec<i8> as JavaSignatureFor>::signature_for(); let results = self.jni_env.call_method( self.java_this.as_obj(), "pixelsWhatever", sig, &[ <&RenderTargetRect as ConvertRustToJValue>::temporary_into_jvalue(&tmp0), <&str as ConvertRustToJValue>::temporary_into_jvalue(&tmp1), <i32 as ConvertRustToJValue>::temporary_into_jvalue(&tmp2), <&AffineTransform as ConvertRustToJValue>::temporary_into_jvalue(&tmp3), ], )?; <Vec<i8> as ConvertJValueToRust>::to_rust(self.jni_env, results) } ：

• INDEX
• INDEX(B:B,1)=INDEX(A:A,2)
• INDEX(B:B,2)=INDEX(A:A,2+10)
