I am trying to read an excel file containg the date and time in the format "dd/mm/yyyy HH:MM:SS". (The excel contains eight columns [Date, Time, data1, data2, data3,data4,data5,data6,data7,data8])

I read the excel file with the code

opts = detectImportOptions("LW.xlsx");
T = readtable("LW.xlsx",opts)
T = 240×8 table
