How can i read a Range in excel which is a table, like in screenshot "Doof" or "excelTab_Zahl" ?
The access to "Dumm" is working but not all the others, despide of they all are listed in the name Manager (see screenshot)
My code:
opts = detectImportOptions('Excel_Read_Write_Matlab.xlsx')
%Working:
data = readtable('Excel_Read_Write_Matlab.xlsx', 'Range', 'Dumm'); %'excelTab_Text'
%Not Working:
data = readtable('Excel_Read_Write_Matlab.xlsx', 'Range', 'Doof'); %'excelTab_Text'
data = readtable('Excel_Read_Write_Matlab.xlsx', 'Range', 'excelTab_Text'); %'excelTab_Text'
data = readtable('Excel_Read_Write_Matlab.xlsx', 'Range', 'excelTab_Zahl'); %'excelTab_Text'
Result of "My code":
opts =
SpreadsheetImportOptions with properties:
Sheet Properties:
Sheet: ''
Replacement Properties:
MissingRule: 'fill'
ImportErrorRule: 'fill'
Variable Import Properties: Set types by name using setvartype
VariableNames: {'A', 'B', 'C' ... and 6 more}
VariableTypes: {'double', 'char', 'char' ... and 6 more}
SelectedVariableNames: {'A', 'B', 'C' ... and 6 more}
VariableOptions: Show all 9 VariableOptions
Access VariableOptions sub-properties using setvaropts/getvaropts
VariableNamingRule: 'modify'
Range Properties:
DataRange: 'A2' (Start Cell)
VariableNamesRange: 'A1'
RowNamesRange: ''
VariableUnitsRange: ''
VariableDescriptionsRange: ''
To display a preview of the table, use preview
Error using readtable
Unable to determine range. Range must be of the form 'A1' (cell), 'A:B' (column-select), '1:5' (row-select), 'A1:B5'
(rectangle-select), or a valid named range in the sheet.

Unfortunately tables are somewhat different to named ranges (although in general it is possible to convert between them). Perhaps this is just an oversight by TMW: you should make an enhancement request:

Maybe I'm wrong, but I assume Matlab can not access Excel range definitions ('Namens-Manager') and you have to address column and row by their identifiers ('A1', 'A:B', ...).
See the opts output. Your range definitions are not listed. Just my assumption.

Have you tried 'readcell' instead of readtable? I encountered that readtable seems to interpret the range differently depending on the cell content. If it's numeric, all data is in rows and the table col names (VariableNames) are just 'Var x', if the cells contain text, the first row in the range is taken as variable names for the table and thus is not part of the data. Not what I assumed. I think it's worth a try.
