API

- setWidth(column,width)

set width for column . width 0(and is default) means auto

  grid.setWidth(0,10); //set the first column with width 10
  grid.setWidth([10,20,5,10]); //set each column

- setColor([column,]color)

set color for column.

if the first param column not set, all column will be set to color .

color could be a string or a function returns string.

colors string support : black red green yellow blue magenta cyan white

  grid.setColor(0,"red"); //set the first column red
  grid.setColor(["red","yellow","green"]); //set each column
  set the second column data `red` when it's greater than 10
  grid.setColor(1,function(content,row,column){
    if(content > 10){
        return "red";
    }
  });
  //equals setColor("red")
  grid.setColor(function(content,row,column){
     return "red";
  });

Notice that colors are managed group by column , and each column could has only one color ever a string or a function.

setColor to the same column will overwrite the color set before.

setColor without param column will overwrite all column color.

  grid.setAlign(0,"center"); //set the first column align center
  grid.setAlign(['left','center' ,'left','right']); //set each column
