我有4個數據幀，我想從selectInput選項中選擇「夾緊槓桿未檢測到關閉 - 錯誤號碼7/31」，但打印兩個數據幀a1和a2，但它分成selectInput兩個選項，如夾緊槓桿關閉未檢測到 - 錯誤編號7/311「夾緊杆關閉未檢測到 - 錯誤編號7/312」以及與數據框b1和b2相同的情況。如何通過從Shiny App中的selectInput（）中選擇一個選項來打印兩個表？
而在第二個表格中，即a2和b2我想上傳文字，我可以上傳它，但是我沒有在表格a1和a2上選擇「未檢測到夾緊杆關閉 - 錯誤編號7/31 」。
a1 <- read.csv(file.path("E:/Puma/Manuals/Smoke tables csv/AT1240E_Smoke_Meter-4.csv"), sep = "," , header = TRUE)
a2 <- read.csv(file.path("E:/Manual/error7.csv"), sep = "," , header = TRUE)
#b1<- read.csv(file.path("E:/Puma/Manuals/Smoke tables csv/AT1240E_Smoke_Meter-21.csv"), sep = "," , header = TRUE)
#b2 <- read.csv(file.path("E:/Manual/error15.csv"), sep = "," , header = TRUE)
