support Rows.IterateColumns

[ankisme]

Description

Rows.Columns return []string, the performance is not good, because user usuall want to iterate []string

the difference is: user want iterate each string, not want []string

so the []string can be removed, because it cost performance, espacially big []string

maybe could support Rows.IterateColumns(), user use it like below

iterateFunc := func(index int, cell string) {

}

rows.IterateColumns(iterateFunc)
