c# - Adjusting column/row width/height based on the number of them -

i have tablelayoutpanel 2 rows , 2 columns called gamegrid.

when button1 pressed want:

a column , row added,

all columns adjusted equal widths,

all rows adjusted equal heights.

this i've tried far:

//add new row , row style gamegrid.rowcount++; gamegrid.rowstyles.add(new system.windows.forms.rowstyle(system.windows.forms.sizetype.absolute, 10));  //change rowstyles entire width / number of rows foreach (rowstyle style in this.gamegrid.rowstyles) {     style.sizetype = sizetype.percent;     style.height = gamegrid.width / gamegrid.rowcount; }  //do same columns gamegrid.columncount++; gamegrid.columnstyles.add(new system.windows.forms.columnstyle(system.windows.forms.sizetype.absolute, 10)); foreach (columnstyle style in this.gamegrid.columnstyles) {     style.sizetype = sizetype.percent;     style.width = gamegrid.height / gamegrid.columncount; } 

but doesn't quite work , end this:

why last column/row longer rest, , work instead?
