How can I parse field with unescaped data?

[yk010123]

I have the following log : 

data=123 params="{"limit":200,"id":["123"] someotherdata

How can I parse the params field to a table so that the final output is 

data	params
123	"{"limit":200,"id":["123"]

if I try table data params

It ends up being : 

data	params
123	{

You already have the data field, so we'll use the rex command to extract the param field.  I'll assume the field ends with the first space.

... | rex "params=(?<params>\S+)"
| table data params
