to sx the variable in workspace... (T= struct2table(Sis);)

to dx the variable in appdesigner as table ( app.UITable_mincap_2.Data=Table_DataAllSystem_Struct(app.Sis);)

in both =1 but only one line is written differently

The information you have given us is that you have a table. You have not shown us the names of the variables in the table, and we have to assume that there might be more columns in the table than you showed us, so we do not know the column numbers involved.

So I put in names that are instructions about how you should change the code.

mask = temp.NameOfVariableWithCurrencyInIt == 'USD';

replace "NameOfVariableWithCurrencyInIt" with the name of the variable which holds the currency name information

usdvalue = subset.NameOfVariableWithNumericvalueInIt;

replace "NameOfVariableWithNumericvalueInIt" with the name of the variable that holds the number that you are showing us

For example maybe the code should look like

temp = app.UITable_mincap_2.Data;
mask = temp.Currency == 'USD';
subset = temp(mask,:);
usdvalue = subset.ExchangeRate;
format long g
usdvalue - 1

if the names of the two variables involved are Currency and ExchangeRate.

If the table happens to hold only the two columns you showed us then you can use

temp = app.UITable_mincap_2.Data;
mask = temp.(1) == 'USD';
subset = temp(mask,:);
usdvalue = subset.(2);
format long g
usdvalue - 1

if the data is not confidential then please store

Table_DataAllSystem_Struct(app.Sis)

into a variable, and save to a mat file and attach the mat file

Experimentally:

It appears that the formatting of rows in the table works on some kind of buffer system having to do with which values are currently visible (the row is scrolled into range, even if the column itself is not.)

The rule appear to be that if anywhere in the current "buffer"-full the row contains a non-integer value, that the entire buffer-full for that column may be formatted as floating point. But only if the values have absolute value less than 1000: from 1000 upwards, the individual non-integer item will be formatted in scientific notation but the integer items in the buffer-full will be formatted as integers.

This is definitely not a behaviour I would have expected.

You could consider using convertvars . However probably varfun with compose would be a better bet: if you just string() a column then it uses odd internal rules for the conversion, whereas if you invoke compose with an anonymous function you could specify the conversion format.
