Row numbering became ... when it exceeds 99th row

i have this jscript that uses a for-loop in populating the rows
for(var i =0;i<300;i++){
obj.setCellText("text",0,i);
obj.setCellText("text",1,i);
obj.setCellText("text",2,i);
}

when it reaches the 100th row the row numbering became a (...)
98
99
...
...
...
...

Please show me how to resolve this

If the columns are too narrow, try widening them (using CSS for columns, setSelectorWidth for the selector column).

obj.setSelectorWidth(50);
