java - How to add extra rows when inserting data (extra empty rows) -


i'm using apache poi write excel file. fill in data in loop.

for example:

header_1|header_2|header3|header_4|header_5|header6 aaaaaaa1|bbbbbb_1|cccccc3| aaaaaaa2|bbbbbb_2|cccccc3| aaaaaaa3|bbbbbb_3|cccccc3| aaaaaaa4|bbbbbb_4|cccccc3|

now it's work fine, need 2 rows each inserted row. want this:

header_1|header_2|header3|header_4|header_5|header6 aaaaaaa1|bbbbbb_1|cccccc3|test1111|test2222|test333                          |testllll|testxxxx|testbbb                          |testllll|testxxxx|testbbb aaaaaaa2|bbbbbb_2|cccccc3|test1111|test2222|test333                          |testllll|testxxxx|testbbb                          |testllll|testxxxx|testbbb aaaaaaa3|bbbbbb_3|cccccc3|test1111|test2222|test333                          |testllll|testxxxx|testbbb                          |testllll|testxxxx|testbbb aaaaaaa4|bbbbbb_4|cccccc3|test1111|test2222|test333                          |testllll|testxxxx|testbbb                          |testllll|testxxxx|testbbb

expected should loop like?

   for(data d: alldata){      row row = sheet.createrow(++row);      cell c = row.createcell(0);      c.setcellvalue("something);      cell c1 = row.createcell(1);      c1.setcellvalue("something1)      //etc..    }

try this:

for(data d: alldata){    row row = sheet.createrow(++row);    cell c = row.createcell(0);    c.setcellvalue("something01");    c = row.createcell(1);    c.setcellvalue("something02")    //etc..     // add rows:    row = sheet.createrow(++row);    c = row.createcell(0);    c.setcellvalue("something11");    c = row.createcell(1);    c.setcellvalue("something12")    //etc.. }

edit: if first row , 2 'empty rows' should share headers 1-3 (and want reduce redundancy) can sheet.addmergedregion(new cellrangeadress(rowfrom, rowto, colfrom, colto) merge columns , rows (but makes excel file unsortable)

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
