How to change/resize EditText in table layout?

I just want to resize the edittext so that it matches my texts. When I insert an edittext in a table layout in column 3 it fills the whole space of column 3 and looks big. I want to change the size. How is it possible? Below is my .xml coding:

<TableRow>
    <TextView
        android:layout_column="1"
        android:text="S"
        android:layout_width="150dp"
        />

    <TextView
        android:layout_column="2"
        android:text="C"
        android:layout_width="75dp" />

    <TextView
        android:layout_column="3"
        android:text="G"/>
</TableRow>

<View
    android:layout_height="2dip"
    android:background="#FF909090" />

<TableRow>
<TextView
    android:layout_column="1"
    android:id="@+id/s1"
    android:text="Medium Text"/>
<TextView
    android:layout_column="2"
    android:id="@+id/c1"
    android:text="Text"/>

<EditText
    android:id="@+id/g1"
    android:layout_column="3" />
</TableRow>

I understand your problem... i tried using wrap_content etc .. but didnt work you have to manually set the height of the EditText.... here's the code:

<?xml version="1.0" encoding="utf-8"?>

<TableRow
    android:id="@+id/tableRow2"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:weightSum="3" >

    <TextView
        android:id="@+id/textView2"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:text="TextView" />

    <TextView
        android:id="@+id/textView5"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:text="TextView" />

    <EditText
        android:id="@+id/editText1"
        android:layout_width="fill_parent"
        android:layout_height="15dp"
        android:layout_weight="1" />



</TableRow>

Try these,

1. Set the "stretchColumn" property of table layout.

2. Set the layout_width of the EditText to "wrap_content".

3. If you want you can fix the size of the EditText by manually setting 
   the layout_width value in dp or dip.

you don't need to specify the column number it picks it itself just place it there if you want edit text to fit the space just strech the column 1&2 in table layout

or you can add linear layout as the table row and assign weight

Try

 <EditText 
        android:layout_width="fill_parent" 
        android:id="@+id/txthwdxml" 
        android:layout_height="wrap_content" />
