The table, readtable, and array2table functions create table arrays. Table arrays provide a convenient way to store tabular data as a MATLAB variable. In App Designer and apps created using the uifigure function, you can specify the Data property as a table array. When a user edits a cell, the Data property updates. To prevent warnings or NaN values that display when users enter invalid data into an editable cell, write a CellEditCallback function to convert the data to the appropriate type. String array - Displays characters and text.Д¬ell array of character vectors - Displays characters and text. true values correspond to selected boxes, whereas false values display cleared boxes.Д¬ell array - Displays any combination of numeric, logical, or character array values. Numeric array - Displays numeric values such as double or single. It might be slightly more readable in a semantic way, but if speed is a concern you'll have to try both version and choose which one gives you the best results.Table array ( uifigure-based apps only) - Displays any combination of data types that table arrays support, such as datetime, duration, and categorical. Now I have seen what goes on into varfun, I am not so sure that this solution will be faster.

go figure.)Дiscussion: Initially I tried to make the varfun solution work (hence the T2 name of the result), and wanted to recommend this one, because I didn't like the table/cell/table conversion of the other solution. Notice that again we had to reassign the column headers on the newly created table ( the irony is varfun choked trying to apply the function on the column headers, but does not re-use or return them in the output.

This will produce the same table than in the example 1 above. T2.Properties.VariableNames = T.Properties.VariableNames For example: cellnum2str = with that, you can now use it to convert your table: %% Use 'varfun' The trick to overcome that, is to send a customised version of num2str which will accept cell arrays. As we saw above, num2str errors when met with a cell array.

If you look at the varfun code at the line indicated by the error, you'll notice that internally, data in your table are converted to cell arrays and the function is applied to that. You'd think that a simple T2 = varfun(, T ) Varfun is for Tables the equivalent of cellfun for cell arrays.

These method is suitable for relatively small tables, as the round trip table/cellarray/table plus the call to cellfun will probably be quite slow for larger tables. Notice that we had to recreate the column names (copied from the initial table), as these are not transferred into the cell array during conversion. Produces a new table containing only strings. T3.Properties.VariableNames = T.Properties.VariableNames T3 = cell2table( cellfun(, table2cell(T), 'uni',0) ) I recreated a table with the same data than in your example.

There are 2 possible way to work around that to convert all your values to character arrays: num2str() is also valid), but it will bomb out if you try to throw a cell array at it (even if all your cells are numeric). However, it can deal with purely numeric arrays (e.g. Yes, num2str accept a single variable of any type and will return a string, so all these operations are valid: > num2str('123')
