Questions about html filter in ng2-smart-table

I have 2 questions:
1 - What configuration do I need to make so that a column filter is activated when typing 1 character? In my implementation it works from 2 characters.
2 - I put the type of a column in my table as html because it shows a stripe with status color. As the column type is html how can I filter this column? Below is an example of a piece of code.

statusRDO: {
title: 'Status RDO',
type: 'html',
valuePrepareFunction: (row, data) => {
if (data.status === "1"){
return `

`;
}
else if (data.status === "2"){
return ``;
}
else if (data.status === "3"){
return ``;
}
},
